/** - * Implements the FASK (Fast Adjacency Skewness) algorithm, which makes decisions for adjacency and orientation using a - * combination of conditional independence testing, judgments of nonlinear adjacency, and pairwise orientation due to - * non-Gaussianity. The reference is this: - *

      - * Sanchez-Romero, R., Ramsey, J. D., Zhang, K., Glymour, M. R., Huang, B., and Glymour, C. (2019). Estimating - * feedforward and feedback effective connections from fMRI time series: Assessments of statistical methods. Network - * Neuroscience, 3(2), 274-30 - *

      - * Some adjustments have been made in some ways from that version, and some additional pairwise options have been added - * from this reference: - *

      - * Hyvärinen, A., and Smith, S. M. (2013). Pairwise likelihood ratios for estimation of non-Gaussian structural equation - * models. Journal of Machine Learning Research, 14(Jan), 111-152. - *

      - * This method (and the Hyvarinen and Smith methods) make the assumption that the data are generated by a linear, - * non-Gaussian causal process and attempts to recover the causal graph for that process. They do not attempt to recover - * the parametrization of this graph; for this a separate estimation algorithm would be needed, such as linear - * regression regressing each node onto its parents. A further assumption is made, that there are no latent common - * causes of the algorithm. This is not a constraint on the pairwise orientation methods, since they orient with respect - * only to the two variables at the endpoints of an edge and so are happy with all other variables being considered - * latent with respect to that single edge. However, if the built-in adjacency search is used (FAS-Stable), the - * existence of latents will throw this method off. - *

      - * As was shown in the Hyvarinen and Smith paper above, FASK works quite well even if the graph contains feedback loops - * in most configurations, including 2-cycles. 2-cycles can be detected fairly well if the FASK left-right rule is - * selected and the 2-cycle threshold set to about 0.1--more will be detected (or hallucinated) if the threshold is set - * higher. As shown in the Sanchez-Romero reference above, 2-cycle detection of the FASK algorithm using this rule is - * quite good. - *

      - * Some edges may be undiscoverable by FAS-Stable; to recover more of these edges, a test related to the FASK left-right - * rule is used, and there is a threshold for this test. A good default for this threshold (the "skew edge threshold") - * is 0.3. For more of these edges, set this threshold to a lower number. - *

      - * It is assumed that the data are arranged so the each variable forms a column and that there are no missing values. - * The data matrix is assumed to be rectangular. To this end, the Tetrad DataSet class is used, which enforces this. - *

      - * Note that orienting a DAG for a linear, non-Gaussian model using the Hyvarinen and Smith pairwise rules is - * alternatively known in the literature as Pairwise LiNGAM--see Hyvärinen, A., and Smith, S. M. (2013). Pairwise - * likelihood ratios for estimation of non-Gaussian structural equation models. Journal of Machine Learning Research, - * 14(Jan), 111-152. We include some of these methods here for comparison. - *

      - * Parameters: - *

      - * faskAdjacencyMethod: 1 # this run FAS-Stable (the one used in the paper). See Algorithm 2. - *

      - * depth: -1. # control the size of the conditional set in the independence tests, setting this to a small integer may - * reduce the running time, but can also result in false positives. -1 means that it will check "all" possible sizes. - *

      - * test: sem-bic-test # test for FAS adjacency - *

      - * score: sem-bic-score - *

      - * semBicRule: 1 # to set the Chickering Rule, used in the original Fask - *

      - * penaltyDiscount: 2 # if using sem-bic as independence test (as in the paper). In the paper this is referred as c. - * Check step 1 and 10 in Algorithm 2 FAS stable. - *

      - * skewEdgeThreshold: 0.3 # See description of Fask algorithm, and step 11 in Algorithm 1 FASK. Threshold to add edges - * that may have been non-inferred because there was a positive/negative cycle that result in a non-zero observed - * relation. - *

      - * faskLeftRightRule: 1 # this run FASK v1, the original FASK from the paper - *

      - * faskDelta: -0.3 # See step 1 and 11 in Algorithm 4 (this is the value set in the paper) - *

      - * twoCycleScreeningThreshold: 0 # not used in the original paper implementation. Added afterwards. You can set it to - * 0.3, for example, to use it as a filter to run Algorithm 3 2-cycle detection, which may take some time to run. - *

      - * orientationAlpha: 0.1 # this was referred in the paper as TwoCycle Alpha or just alpha, the lower it is, the lower - * the chance of inferring a two cycle. Check steps 17 to 28 in Algorithm 3: 2 Cycle Detection Rule. - *

      - * structurePrior: 0 # prior on the number of parents. Not used in the paper implementation. - *

The reference is this: + *

      + * Sanchez-Romero, R., Ramsey, J. D., Zhang, K., Glymour, M. R., Huang, B., and Glymour, C. (2019). Estimating + * feedforward and feedback effective connections from fMRI time series: Assessments of statistical methods. Network + * Neuroscience, 3(2), 274-30 + *

      + * Some adjustments have been made in some ways from that version, and some additional pairwise options have been added + * from this reference: + *

      + * Hyvärinen, A., and Smith, S. M. (2013). Pairwise likelihood ratios for estimation of non-Gaussian structural equation + * models. Journal of Machine Learning Research, 14(Jan), 111-152. + *

      + * This method (and the Hyvarinen and Smith methods) make the assumption that the data are generated by a linear, + * non-Gaussian causal process and attempts to recover the causal graph for that process. They do not attempt to recover + * the parametrization of this graph; for this a separate estimation algorithm would be needed, such as linear + * regression regressing each node onto its parents. A further assumption is made, that there are no latent common + * causes of the algorithm. This is not a constraint on the pairwise orientation methods, since they orient with respect + * only to the two variables at the endpoints of an edge and so are happy with all other variables being considered + * latent with respect to that single edge. However, if the built-in adjacency search is used (FAS-Stable), the + * existence of latents will throw this method off. + *

      + * As was shown in the Hyvarinen and Smith paper above, FASK works quite well even if the graph contains feedback loops + * in most configurations, including 2-cycles. 2-cycles can be detected fairly well if the FASK left-right rule is + * selected and the 2-cycle threshold set to about 0.1--more will be detected (or hallucinated) if the threshold is set + * higher. As shown in the Sanchez-Romero reference above, 2-cycle detection of the FASK algorithm using this rule is + * quite good. + *

      + * Some edges may be undiscoverable by FAS-Stable; to recover more of these edges, a test related to the FASK left-right + * rule is used, and there is a threshold for this test. A good default for this threshold (the "skew edge threshold") + * is 0.3. For more of these edges, set this threshold to a lower number. + *

      + * It is assumed that the data are arranged so each variable forms a column and that there are no missing values. + * The data matrix is assumed to be rectangular. To this end, the Tetrad DataSet class is used, which enforces this. + *

      + * Note that orienting a DAG for a linear, non-Gaussian model using the Hyvarinen and Smith pairwise rules is + * alternatively known in the literature as Pairwise LiNGAM--see Hyvärinen, A., and Smith, S. M. (2013). Pairwise + * likelihood ratios for estimation of non-Gaussian structural equation models. Journal of Machine Learning Research, + * 14(Jan), 111-152. We include some of these methods here for comparison. + *

      + * Parameters: + *

      + * faskAdjacencyMethod: 1 # this run FAS-Stable (the one used in the paper). See Algorithm 2. + *

      + * depth: -1. # control the size of the conditional set in the independence tests, setting this to a small integer may + * reduce the running time, but can also result in false positives. -1 means that it will check "all" possible sizes. + *

      + * test: sem-bic-test # test for FAS adjacency + *

      + * score: sem-bic-score + *

      + * semBicRule: 1 # to set the Chickering Rule, used in the original Fask + *

      + * penaltyDiscount: 2 # if using sem-bic as independence test (as in the paper). In the paper this is referred as c. + * Check step 1 and 10 in Algorithm 2 FAS stable. + *

      + * skewEdgeThreshold: 0.3 # See description of Fask algorithm, and step 11 in Algorithm 1 FASK. Threshold to add edges + * that may have been non-inferred because there was a positive/negative cycle that result in a non-zero observed + * relation. + *

      + * faskLeftRightRule: 1 # this run FASK v1, the original FASK from the paper + *

      + * faskDelta: -0.3 # See step 1 and 11 in Algorithm 4 (this is the value set in the paper) + *

      + * twoCycleScreeningThreshold: 0 # not used in the original paper implementation. Added afterwards. You can set it to + * 0.3, for example, to use it as a filter to run Algorithm 3 2-cycle detection, which may take some time to run. + *

      + * orientationAlpha: 0.1 # this was referred in the paper as TwoCycle Alpha or just alpha, the lower it is, the lower + * the chance of inferring a two cycle. Check steps 17 to 28 in Algorithm 3: 2 Cycle Detection Rule. + *

      + * structurePrior: 0 # prior on the number of parents. Not used in the paper implementation. + *

Checks are done for adding two cycles. The two-cycle - * checks do not require non-Gaussianity. The robust skew orientation of edges left or right does. + * Implements the FASK (Fast Adjacency Skewness) algorithm, which makes decisions for adjacency and orientation using a + * combination of conditional independence testing, judgments of nonlinear adjacency, and pairwise orientation due to + * non-Gaussianity. The reference is this: + *

      + * Sanchez-Romero, R., Ramsey, J. D., Zhang, K., Glymour, M. R., Huang, B., and Glymour, C. (2019). Estimating + * feedforward and feedback effective connections from fMRI time series: Assessments of statistical methods. Network + * Neuroscience, 3(2), 274-30 + *

      + * Some adjustments have been made in some ways from that version, and some additional pairwise options have been added + * from this reference: + *

      + * Hyvärinen, A., and Smith, S. M. (2013). Pairwise likelihood ratios for estimation of non-Gaussian structural equation + * models. Journal of Machine Learning Research, 14(Jan), 111-152. + *

      + * This method (and the Hyvarinen and Smith methods) make the assumption that the data are generated by a linear, + * non-Gaussian causal process and attempts to recover the causal graph for that process. They do not attempt to recover + * the parametrization of this graph; for this a separate estimation algorithm would be needed, such as linear + * regression regressing each node onto its parents. A further assumption is made, that there are no latent common + * causes of the algorithm. This is not a constraint on the pairwise orientation methods, since they orient with respect + * only to the two variables at the endpoints of an edge and so are happy with all other variables being considered + * latent with respect to that single edge. However, if the built-in adjacency search is used (FAS-Stable), the + * existence of latents will throw this method off. + *

      + * As was shown in the Hyvarinen and Smith paper above, FASK works quite well even if the graph contains feedback loops + * in most configurations, including 2-cycles. 2-cycles can be detected fairly well if the FASK left-right rule is + * selected and the 2-cycle threshold set to about 0.1--more will be detected (or hallucinated) if the threshold is set + * higher. As shown in the Sanchez-Romero reference above, 2-cycle detection of the FASK algorithm using this rule is + * quite good. + *

      + * Some edges may be undiscoverable by FAS-Stable; to recover more of these edges, a test related to the FASK left-right + * rule is used, and there is a threshold for this test. A good default for this threshold (the "skew edge threshold") + * is 0.3. For more of these edges, set this threshold to a lower number. + *

      + * It is assumed that the data are arranged so each variable forms a column and that there are no missing values. The + * data matrix is assumed to be rectangular. To this end, the Tetrad DataSet class is used, which enforces this. + *

      + * Note that orienting a DAG for a linear, non-Gaussian model using the Hyvarinen and Smith pairwise rules is + * alternatively known in the literature as Pairwise LiNGAM--see Hyvärinen, A., and Smith, S. M. (2013). Pairwise + * likelihood ratios for estimation of non-Gaussian structural equation models. Journal of Machine Learning Research, + * 14(Jan), 111-152. We include some of these methods here for comparison. + *

      + * Parameters: + *

      + * depth: -1. # control the size of the conditional set in the independence tests, setting this to a small integer may + * reduce the running time, but can also result in false positives. -1 means that it will check "all" possible sizes. + *

      + * score: sem-bic-score + *

      + * semBicRule: 1 # to set the Chickering Rule, used in the original Fask + *

      + * penaltyDiscount: 2 # if using sem-bic as independence test (as in the paper). In the paper this is referred as c. + * Check step 1 and 10 in Algorithm 2 FAS stable. + *

      + * skewEdgeThreshold: 0.3 # See description of Fask algorithm, and step 11 in Algorithm 1 FASK. Threshold to add edges + * that may have been non-inferred because there was a positive/negative cycle that result in a non-zero observed + * relation. + *

      + * faskLeftRightRule: 1 # this run FASK v1, the original FASK from the paper + *

      + * faskDelta: -0.3 # See step 1 and 11 in Algorithm 4 (this is the value set in the paper) + *

      + * orientationAlpha: 0.1 # this was referred in the paper as TwoCycle Alpha or just alpha, the lower it is, the lower + * the chance of inferring a two cycle. Check steps 17 to 28 in Algorithm 3: 2 Cycle Detection Rule. + *

      + * structurePrior: 0 # prior on the number of parents. Not used in the paper implementation. + *

Added a timer to call updates every second to "# independencies" and "# dependencies" labels in MarkovCheckEditor. Created a new interface, ModelObserver, and integrated observer pattern in MarkovCheck to notify observers of changes. These measures ensure that data is updated in real-time and errors related to out of range indices are avoided. --- .../tetradapp/editor/MarkovCheckEditor.java | 49 +++++++++++++++---- .../edu/cmu/tetrad/search/MarkovCheck.java | 20 +++++++- .../edu/cmu/tetrad/search/ModelObserver.java | 5 ++ 3 files changed, 63 insertions(+), 11 deletions(-) create mode 100644 tetrad-lib/src/main/java/edu/cmu/tetrad/search/ModelObserver.java diff --git a/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/MarkovCheckEditor.java b/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/MarkovCheckEditor.java index b11cf185bd..7529b849c6 100644 --- a/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/MarkovCheckEditor.java +++ b/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/MarkovCheckEditor.java @@ -690,14 +690,14 @@ public int getRowCount() { } public Object getValueAt(int rowIndex, int columnIndex) { - if (rowIndex > model.getResults(true).size()) { - return null; - } - if (columnIndex == 0) { return rowIndex + 1; } + if (rowIndex >= model.getResults(true).size()) { + return null; + } + IndependenceResult result = model.getResults(true).get(rowIndex); if (columnIndex == 1) { @@ -781,8 +781,22 @@ public void mouseClicked(MouseEvent e) { addFilterPanel(model, tableModelIndep, tableIndep, tableBox, flipEscapesIndep); + Box b10 = Box.createHorizontalBox(); + b10.add(Box.createHorizontalGlue()); JLabel label = new JLabel("Table contents can be selected and copied in to, e.g., Excel."); - tableBox.add(label, BorderLayout.SOUTH); + b10.add(label); + b10.add(Box.createHorizontalStrut(20)); + + JLabel label1 = new JLabel("# independencies = " + model.getResults(true).size()); + b10.add(label1); + b10.add(Box.createHorizontalGlue()); + + // Setup a Timer to call update every 5 seconds + javax.swing.Timer timer = new javax.swing.Timer(1000, + e -> label1.setText("# independencies = " + model.getResults(true).size())); + timer.start(); + + tableBox.add(b10, BorderLayout.SOUTH); setLabelTexts(); @@ -1094,11 +1108,28 @@ public void mouseClicked(MouseEvent e) { JScrollPane scroll = new JScrollPane(tableDep); tableBox.add(scroll); - Box a3 = Box.createHorizontalBox(); +// Box a3 = Box.createHorizontalBox(); +// JLabel label = new JLabel("Table contents can be selected and copied in to, e.g., Excel."); +// a3.add(label); +// a3.add(Box.createHorizontalGlue()); +// tableBox.add(label); + + Box b10 = Box.createHorizontalBox(); + b10.add(Box.createHorizontalGlue()); JLabel label = new JLabel("Table contents can be selected and copied in to, e.g., Excel."); - a3.add(label); - a3.add(Box.createHorizontalGlue()); - tableBox.add(label); + b10.add(label); + b10.add(Box.createHorizontalStrut(20)); + + JLabel label1 = new JLabel("# dependencies = " + model.getResults(true).size()); + b10.add(label1); + b10.add(Box.createHorizontalGlue()); + + // Setup a Timer to call update every 5 seconds + javax.swing.Timer timer = new javax.swing.Timer(1000, + e -> label1.setText("# dependencies = " + model.getResults(true).size())); + timer.start(); + + tableBox.add(b10, BorderLayout.SOUTH); setLabelTexts(); diff --git a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/MarkovCheck.java b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/MarkovCheck.java index f29e0d7cf6..f9672ad297 100644 --- a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/MarkovCheck.java +++ b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/MarkovCheck.java @@ -1077,9 +1077,9 @@ private double getBinomialPValue(List pValues, double alpha) { */ private List getResultsLocal(boolean indep) { if (indep) { - return this.resultsIndep; + return new ArrayList<>(this.resultsIndep); } else { - return this.resultsDep; + return new ArrayList<>(this.resultsDep); } } @@ -1156,6 +1156,22 @@ public double getAndersonDarlingPValue(List visiblePairs) { return 1. - generalAndersonDarlingTest.getProbTail(pValues.size(), aSquaredStar); } + private List observers = new ArrayList<>(); + + public void addObserver(ModelObserver observer) { + observers.add(observer); + } + + public void removeObserver(ModelObserver observer) { + observers.remove(observer); + } + + public void notifyObservers() { + for (ModelObserver observer : observers) { + observer.update(); + } + } + /** * A single record for the results of the Markov check. * diff --git a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/ModelObserver.java b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/ModelObserver.java new file mode 100644 index 0000000000..da951277f5 --- /dev/null +++ b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/ModelObserver.java @@ -0,0 +1,5 @@ +package edu.cmu.tetrad.search; + +public interface ModelObserver { + void update(); +} From 8de2c9d4ddfc8c0050097c3e02900105dfafe183 Mon Sep 17 00:00:00 2001 From: jdramsey Date: Sun, 19 May 2024 04:13:16 -0400 Subject: [PATCH 039/320] Refactor MarkovCheck to implement clear method Added a clear method to the MarkovCheck class to avoid redundant code.

The commit added two new options and associated handling logic for these path types under the methodBox. It extended the `tetrad-lib`'s `Paths` with a method specific to PAGs. Also, a redundant import was removed from `PathsAction`. The extension for PAGs aids users in exploring paths between certain nodes for setups with Partially Annotated Graphs, thus providing new tools for graph exploration.

These constructors enable initialization of GridSearchModel with different combinations of arguments such as KnowledgeBoxModel, GraphSource, DataWrapper, and Parameters. This provides more flexibility when initializing GridSearchModel instances. Also, adjustments have made in some method's documentation for clarity and old unused method 'setWeight' was deleted. --- .../cmu/tetradapp/model/GridSearchModel.java | 64 +++++++++++++------ 1 file changed, 44 insertions(+), 20 deletions(-) diff --git a/tetrad-gui/src/main/java/edu/cmu/tetradapp/model/GridSearchModel.java b/tetrad-gui/src/main/java/edu/cmu/tetradapp/model/GridSearchModel.java index 2c89a55e42..b86303592e 100644 --- a/tetrad-gui/src/main/java/edu/cmu/tetradapp/model/GridSearchModel.java +++ b/tetrad-gui/src/main/java/edu/cmu/tetradapp/model/GridSearchModel.java @@ -167,6 +167,15 @@ public GridSearchModel(Parameters parameters) { initializeIfNull();

          Date: Tue, 4 Jun 2024 00:38:32 -0400 Subject: [PATCH 117/320] Implement option for internal algorithmic randomness In this commit, an option has been added to allow for internal randomness in the search algorithm. This feature is toggleable through setAllowInternalRandomness().

Also, removed the unused 'score' and 'start' variables and unnecessary methods in LvLiteDsepFriendly. Also, optimized the 'search' method and updated the verbose logs for better clarity. --- .../java/edu/cmu/tetrad/search/Grasp.java | 2 +- .../java/edu/cmu/tetrad/search/LvLite.java | 440 +++++++------- .../cmu/tetrad/search/LvLiteDsepFriendly.java | 536 +----------------- 3 files changed, 241 insertions(+), 737 deletions(-) diff --git a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/Grasp.java b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/Grasp.java index fe8ac42d67..94d65068e2 100644 --- a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/Grasp.java +++ b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/Grasp.java @@ -153,7 +153,7 @@ public Grasp(@NotNull IndependenceTest test) { public Grasp(@NotNull IndependenceTest test, Score score) { this.test = test; this.score = score; - this.variables = new ArrayList<>(score.getVariables()); + this.variables = new ArrayList<>(test.getVariables()); } /** diff --git a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/LvLite.java b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/LvLite.java index 8942663209..e316e4ae58 100644 --- a/tetrad-lib/src/main/java/edu/cmu/tetrad/search/LvLite.java +++ b/tetrad-lib/src/main/java/edu/cmu/tetrad/search/LvLite.java @@ -119,155 +119,13 @@ public LvLite(Score score) { * * @param pag The Graph to be reoriented. */ - private void reorientWithCircles(Graph pag) { + private static void reorientWithCircles(Graph pag, boolean verbose) { if (verbose) { TetradLogger.getInstance().log("Orient all edges in PAG as o-o:"); } pag.reorientAllWith(Endpoint.CIRCLE); } - /** - * Run the search and return s a PAG. - * - * @return The PAG. - */ - public Graph search() { - List nodes = this.score.getVariables(); - - if (nodes == null) { - throw new NullPointerException("Nodes from test were null."); - } - - if (verbose) { - TetradLogger.getInstance().log("===Starting LV-Lite==="); - } - - if (verbose) { - TetradLogger.getInstance().log("Running BOSS to get CPDAG and best order."); - } - - // BOSS seems to be doing better here. - var suborderSearch = new Boss(score); - suborderSearch.setKnowledge(knowledge); - suborderSearch.setResetAfterBM(true); - suborderSearch.setResetAfterRS(true); - suborderSearch.setVerbose(false); - suborderSearch.setUseBes(useBes); - suborderSearch.setUseDataOrder(useDataOrder); - suborderSearch.setNumStarts(numStarts); - var permutationSearch = new PermutationSearch(suborderSearch); - permutationSearch.setKnowledge(knowledge); - permutationSearch.search(); - var best = permutationSearch.getOrder(); - - if (verbose) { - TetradLogger.getInstance().log("Best order: " + best); - } - - var scorer = new TeyssierScorer(null, score); - scorer.score(best); - scorer.bookmark(); - - if (verbose) { - TetradLogger.getInstance().log("Initializing PAG to BOSS CPDAG."); - TetradLogger.getInstance().log("Initializing scorer with BOSS best order."); - } - - var cpdag = scorer.getGraph(true); - var pag = new EdgeListGraph(cpdag); - scorer.score(best); - - FciOrient fciOrient = new FciOrient(null); - - fciOrient.setCompleteRuleSetUsed(completeRuleSetUsed); - fciOrient.setDoDiscriminatingPathColliderRule(false); - fciOrient.setDoDiscriminatingPathTailRule(false); - fciOrient.setMaxPathLength(maxPathLength); - fciOrient.setKnowledge(knowledge); - fciOrient.setVerbose(verbose); - - if (verbose) { - TetradLogger.getInstance().log("Collider orientation and edge removal."); - } - - // The main procedure. - Set unshieldedColliders = new HashSet<>(); - Set _unshieldedColliders; - - do { - _unshieldedColliders = new HashSet<>(unshieldedColliders); - orientCollidersAndRemoveEdges(pag, fciOrient, best, scorer, unshieldedColliders, cpdag); - } while (!unshieldedColliders.equals(_unshieldedColliders)); - - finalOrientation(fciOrient, pag, scorer); - - return GraphUtils.replaceNodes(pag, this.score.getVariables()); - } - - /** - * Sets the knowledge used in search. - * - * @param knowledge This knowledge. - */ - public void setKnowledge(Knowledge knowledge) { - this.knowledge = new Knowledge(knowledge); - } - - /** - * Sets whether the complete rule set should be used during the search algorithm.

Subject: [PATCH 124/320] Refactor collider orientation and remove unused
 parameters

The collider orientation logic in the LvLite.java and LvLiteDsepFriendly.java files is refactored and made more concise. Unnecessary parameters and methods related to depth settings for search algorithms in these files are also removed. The default value for 'doDiscriminatingPathColliderRule' is now set to true in the manual index.html file.

Subject: [PATCH 125/320] Refactor and optimize LvLite and related classes

Revamped the recallUnshieldedTriples method in LvLite to clean up its operations, improving its efficiency. Enhanced LvLiteDsepFriendly by altering various parameters for better performance. The DagToPag has been revised with more extensive inline documentation and notes. The FciOrient class was updated to ensure that every endpoint and edge changing operation correctly sets the change flag for better responsiveness to alterations.

Subject: [PATCH 126/320] Refactor type conversion and remove readResolve
 method

The code has been refactored to include type checking before doing a type conversion, improving error handling. Unnecessary import statements have been removed. Additionally, white spaces and line alignment have been corrected for better readability. The readResolve method in the NodeType class, which was not being used, has also been removed.

Subject: [PATCH 127/320] Add equality threshold and optimize performance in
 LV-Lite

In the LV-Lite algorithm, the equalityThreshold variable has been added to control the score drop after the tucking process. Also, the algorithm computation process has been optimized to reduce unnecessary thread creation. In PermutationSearch, a new method of managing the Knowledge object's tiers and variables has been implemented. Minor adjustments have also been made in miscellaneous parts of the code to improve overall algorithm performance and functionality.

The output directory creation process was also streamlined. --- .../tetradapp/editor/GridSearchEditor.java | 47 ++++---- .../edu/cmu/tetradapp/editor/LoadGraph.java | 3 +- .../tetradapp/editor/LoadGraphAmatCpdag.java | 3 +- .../tetradapp/editor/LoadGraphAmatPag.java | 3 +- .../cmu/tetradapp/editor/LoadGraphJson.java | 3 +- .../cmu/tetradapp/editor/LoadGraphTxt.java | 3 +- .../cmu/tetradapp/model/GridSearchModel.java | 61 +++++++---- .../cmu/tetrad/algcomparison/Comparison.java | 101 +++++------------- .../algcomparison/TimeoutComparison.java | 74 +++---------- .../examples/ExampleCompareFromFiles.java | 2 - .../examples/ExampleCompareSimulation.java | 3 - .../examples/ExampleCompareSimulation2.java | 3 - .../examples/ExampleNonlinearSave.java | 1 - .../algcomparison/examples/ExampleSave.java | 1 - .../examples/MVPCompareFromFiles.java | 2 - .../tetrad/algcomparison/examples/Save.java | 1 - .../examples/SaveDGSimulations.java | 1 - .../algcomparison/examples/TestBoss.java | 3 - .../examples/TestDegenerateGaussian.java | 3 - .../java/edu/cmu/tetrad/search/BossPag.java | 2 - .../edu/cmu/tetrad/search/MarkovCheck.java | 2 +- .../conditions/BryanSensitivityStudy.java | 3 - .../conditions/ExampleCompareFromFiles.java | 2 - .../conditions/ExampleCompareSimulation.java | 3 - .../ExampleCompareSimulationDiscrete.java | 3 - .../conditions/ExampleFirstInflection.java | 3 - .../examples/conditions/ExampleStars.java | 3 - .../examples/conditions/LingamStudy.java | 3 - .../test/SpecialExampleSimulationClark.java | 3 - .../TestConditionalGaussianSimulation.java | 3 - .../java/edu/cmu/tetrad/test/TestCopy.java | 3 - .../tetrad/test/TestGenerateMixedData.java | 3 - .../java/edu/cmu/tetrad/test/TestGrasp.java | 18 ---- .../cmu/tetrad/test/TestImagesSimulation.java | 3 - .../tetrad/test/TestKunMeasurementError.java | 3 - .../cmu/tetrad/test/TestSimulatedFmri.java | 9 -- .../cmu/tetrad/test/TestSimulatedFmri2.java | 3 - .../cmu/tetrad/test/TestSimulatedFmri3.java | 6 -- 38 files changed, 118 insertions(+), 278 deletions(-) diff --git a/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/GridSearchEditor.java b/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/GridSearchEditor.java index 61ce184181..a944cb5c2e 100644 --- a/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/GridSearchEditor.java +++ b/tetrad-gui/src/main/java/edu/cmu/tetradapp/editor/GridSearchEditor.java @@ -6,12 +6,16 @@ import edu.cmu.tetrad.algcomparison.score.ScoreWrapper;

The methods obtain counts and represent them as ratios for comparison. Also updated depth control in search algorithms LvLite and LvLiteDsepFriendly to provide more flexibility in configuring search depth.

Subject: [PATCH 141/320] Add graph viewing functionality to GridSearch GUI

Modified the GridSearch module to provide a graph viewing functionality. Added a new tab for viewing graphs, which allows the user to select the simulation, algorithm, and graph index for viewing the graph from the comparison table. Updated the JComboBoxes to handle changes in selection and reflect the respective graph on the workbench panel. Removed unused codes and fixed the formatting and serialization of some parameters.

Subject: [PATCH 142/320] Add depth setting methods and refactor statistics
 calculation

Method documentation for setting depth in certain search classes has been added. Additionally, the statistics calculation function in the Comparison class has been refactored to accept an additional `AlgorithmWrapper` argument, leading to changes in several method calls and the `AlgorithmTask` constructor. The `AlgorithmTask` class now also includes an `algorithmWrappers` field to support this change.

Subject: [PATCH 144/320] Make GUI components transient and refactor button
 creation

The commit makes all JTextArea, JButton, JComboBox, JScrollPane, and JTabbedPane components in GridSearchEditor transient. This change is to avoid potential issues in serialization of GUI components. Additionally, this refactor moves the creation code for the 'Edit Utilities' button into a separate helper method. This method is called in appropriate places, improving code readability and facilitating reuse.

Subject: [PATCH 145/320] Redirect verbose output to System.out and ensure
 parameter serialization

The commit mainly directs verbose output to System.out instead of a PrintStream object. This change is reflected across different modules like Fas, FgesMb, SpFci, and more. Along with this, validation has been added to check whether parameters assigned are serializable before setting them in the Parameters class. This aims to avoid errors while saving the parameters object as a field. Unnecessary parameter "printStream" was also removed from Params and its usage in various classes like GridSearchModel and Comparison has been updated.

Subject: [PATCH 147/320] Remove unused MagSemBicScore and add new Scoring
 Implementations

Removed unused MagSemBicScore from the edu.cmu.tetrad.algcomparison.score package. This file was not being used or referenced in the codebase. Also, added new scoring implementation files MagDgBicScore and MagCgBicScore to edu.cmu.tetrad.search.work_in_progress package. Made minor adjustments in GridSearchModel for print streams.

Subject: [PATCH 148/320] Refactor likelihood tests and update data handling in
 multiple files

This commit includes refactoring of the likelihood tests in 'IndTestFisherZ', 'IndTestConditionalGaussianLrt' and 'IndTestDegenerateGaussianLrt' files. This includes changes in the way rows are handled. Additionally, several unnecessary loops and verbose logs have been removed to make the code more efficient. The datatype tests in 'tetrad-lib.properties' have been updated and some minor modifications in 'MarkovCheck', 'BossPag', 'MagCgScore' and other files to improve performance.

Subject: [PATCH 149/320] Reduce histogram bins and optimize variable removal
 in Markov check

The number of bins in the histogram has been reduced from 20 to 10 for compression. Moreover, an optimization has been added to the Markov check algorithm to remove extraneous variables more efficiently. The check for variable removal will now be performed in the specific sections of the algorithm where it is necessary.

Subject: [PATCH 151/320] Implement prevention of graph cycles in Meek rules

The Meek rules now include a provision to prevent cycles in the graph. The option to prevent cycles can be toggled on by the user. A check has been added to ensure that new cycles are not created while adding arbitrary unshielded colliders. The colliderAllowed method has been updated to include a check on graph ancestors. This prevents colliders from being activated where they would introduce cycles, thus maintaining the acyclic nature of the graph.

Subject: [PATCH 153/320] Added meekPreventCycles flag with default setting

The meekPreventCycles flag has been added and set to true by default. This will prevent the creation of cycles in the graph by adding arbitrary unshielded colliders. Users have the option to turn this setting off to avoid cycle prevention, which allows the PC algorithm to always output a CPDAG.

Subject: [PATCH 154/320] Refactor MeekRules class with better documentation

The refactoring of the MeekRules class has resulted in better documentation and more readable code structure. This includes more detailed comments for class attributes and essential methods, minor code reordering for improved readability, and slight adjustments to variable explanations to enhance clarity. Changes should help future developers understand the functionality and purpose of this class better.

Subject: [PATCH 155/320] Refactor logging and collider checks in MeekRules and
 PcCommon

Revised logging to be controlled by a flag and added explanatory comments for increased readability. In MeekRules, logger is used to prevent cycles while orienting edges. In PcCommon, the method 'colliderAllowed' was moved to a more appropriate location and all the logging in the file was modified to use the updated log method.

Subject: [PATCH 156/320] Move directed edge addition in MeekRules

The addition of directed edges in the MeekRules class has been relocated within the code. It now falls after the verbose conditions. This ensures that all the necessary conditions are checked before modification of the graph structure. It forms part of the process of preventing new cycles in the graph.

Subject: [PATCH 157/320] Add ability to prevent cycles in Meek orientation

Added an option in the Meek rules to prevent cycles when orienting the graph structure. This was accomplished by including a 'meekPreventCycles' flag to the relevant search classes, which instructs them to avoid constructing cycles during the search process. This feature was also integrated into the corresponding test cases.

Subject: [PATCH 158/320] Replace "meekPreventCycles" with "guaranteeCpdag"
 across multiple files

The parameter "meekPreventCycles" has been replaced with "guaranteeCpdag" in several classes to better describe its functionality. This change is aimed to ensure the output to be a Consensus Partially Directed Acyclic Graph (CPDAG) in the search. The commit also involves updates in corresponding test cases and documentations.

Subject: [PATCH 160/320] Enable cycle prevention in MeekRules and improve
 documentation

The value for `meekPreventCycles` has been changed from false to true in both `Fges.java` and `FgesMb.java` to prevent cycles in Meek rules. Additionally, extensive comments and documentation have been introduced in several classes including `Comparison.java`, `GraphTransforms.java`, and `MeekRules.java` to clarify methods' purposes and parameters. Some unnecessary cycle checking code in `MeekRules.java` has been commented out.

Subject: [PATCH 161/320] Add additional argument in compareFromSimulations
 method

An additional argument has been included in the compareFromSimulations method in the Comparison.java file. This change allows for a null value to be passed for improved flexibility and compatibility in certain situations where the previous parameters may not be required or available.

Subject: [PATCH 164/320] Refactor graph comparison methods and adjust collider
 orientation

The main changes in this commit are the refactoring of graph comparison methods to make them more efficient and the adjustments to the collider orientation process. The graph comparison methods' refactoring includes the update of the `getComparisonGraph` method both in `Misclassifications.java` and `EdgewiseComparisonModel.java`. Additionally, the collider orientation process in the `LvLite.java` class has been updated to accommodate changes to the score metrics. The equality threshold has also been adjusted.

Subject: [PATCH 165/320] Rename orientCollidersAndRemoveEdges to
 orientAndRemove

The function orientCollidersAndRemoveEdges has been renamed to orientAndRemove to more accurately reflect its functionality. The change has been reflected wherever this method is called throughout the codebase. This provides a more intuitive understanding of the method's role in the lvLite and lvLiteDsepFriendly classes.

Subject: [PATCH 166/320] Update LvLite algorithm mechanics

The LvLite algorithm has undergone changes including importing Math.exp instead of Math.abs. Renamed "best_score" variable as "bestScore" and applied this convention throughout the score calculations. The condition to compare "bestScore" and "newScore" has also been updated where the variable "bayesFactor" is used. The "doRequiredOrientations" method has also been slightly refactored.

Subject: [PATCH 167/320] Rename "equalityThreshold" to "bayesFactorThreshold"

The term "equalityThreshold" was renamed to "bayesFactorThreshold" to avoid confusion and ensure consistency. The change affects the LV-Lite procedure where the new term "bayesFactorThreshold" is now used to prevent score drops more than 2 * Bayes factor. This is because the BIC scores are calculated using the formula 2L - c k ln N. The codebase was updated across multiple files accordingly.

Subject: [PATCH 168/320] Update description in LV-Lite procedure documentation

The documentation inaccurately described the Bayes factor threshold in the LV-Lite procedure. This update corrects this by clarifying that it should be the Log Bayes factor threshold instead.

Subject: [PATCH 169/320] Update LvLite classes and methods to use
 allowableThreshold

Refactored all instances of bayesFactorThreshold in the LvLite and LvLiteDsepFriendly classes to allowableThreshold. This includes method names, variable names, and comments. Also updated related classes and methods to reflect this change. Bayes Factor computations have been removed as they are no longer necessary with the new threshold metric. This change improves readability and ensures consistency across classes and methods.

Subject: [PATCH 172/320] Update rules and methods to repair faulty PAGs in
 various graph-related classes

This commit implements changes to GraphEditor, BFci, LvLiteDsepFriendly, GraphUtils, DagEditor, SpFci, SemGraphEditor, FciOrient, Fci, and GraspFci classes. The primary change involved is the introduction of rules and methods to repair faulty PAGs (probability assessment graphs). Such changes aid in handling cases where the PAG may have inconsistencies or errors, allowing for more robust graph evaluations. In addition, adjustments have been made to keybindings for pathsAction in various editors, changing them from ALT+P to ALT+T.

Subject: [PATCH 174/320] Update node replacement in TestCheckMarkov

The nodes of the estimated CPDAG graph are now replaced with nodes from the true graph in the TestCheckMarkov test. This modification was made in the SemBicScore test case where the PermutationSearch is used. The unnecessary line break was also removed.

Subject: [PATCH 177/320] Refactor code and fix orientation issue

The commit includes changes majorly to fix orientation issues and also includes some code refactoring. Specific changes include the amendment of tuck variable order, verbose mode logging added for tracing decisions in graphical models, altering some conditional check variables, altered some method call sequences, switching algorithm settings, and a fix to make sure "doDiscriminatingPathTailRule" and "doDiscriminatingPathColliderRule" are set to `true`. Furthermore, the external graph usage in 'Fges' class has been removed.

Subject: [PATCH 178/320] Update repairFaultyPag method and enhance logging in
 GraphUtils

The 'repairFaultyPag' method in GraphUtils has been updated to not return a graph. Now, it directly modifies the graph input parameter. Additionally, this change was propagated to the classes that call this method: Bfci, Fci, GraspFci, Gfci, LvLite, and SpFci. Also, logging details have been added in GFci.java to indicate the start and end of various stages in the process.

Subject: [PATCH 179/320] Refactor LvLite and LvLiteDsepFriendly classes

The code has been refactored to remove unnecessary comments, methods and improve readability. The `LvLite.java` and `LvLiteDsepFriendly.java` files were mostly affected. The `cpdag` parameter has been removed from multiple methods, reducing redundancy. The retrieval of Graph 'pag' has also been improved by directly getting it from the scorer object in the 'search' method of 'LvLite.java'.

Subject: [PATCH 180/320] Update calculation methods in GraphUtils and optimize
 various search methods

In the GraphUtils class, several calculation methods like pathString() and repairFaultyPag() have been updated. This includes adding more details for the parameter of pathString, and modifying the logic for repairing a faulty PAG. Corresponding changes have also been made in the classes using these methods. Some search methods, such as Fci(), BFci(), GraspFci, LvLite, and SpFci, have been streamlined to improve the algorithm efficiency. The change to LvLite also includes removing extra edges with larger conditioning sets for improving the search accuracy.

+     * Otherwise, two types of repairs are attempted. First, if there is an edge x <-> y with a path x ~~> y,
+     * then the edge is oriented to x --> y. Such an edge cannot be x <-- y on pain of a cycle. Also, it cannot be
+     * x <-> y because the bidirected-edge semantics prohibits it (the problem we're trying to fix). So it must
+     * actually be x --> y. The basic issue here is that to know the edge is not bidirected, we need to be able to
+     * "peer into the future" of the orientation process, which we can't do. As it turns out, this edge can't have been
+     * bidirected in the first place, because it would have been oriented to x --> y in the first place had we known
+     * that x ~~> y. So it's making a claim about non-causality that can't be supported. So we just fix it in
+     * post-processing.
+     * 
            
+     * Second, if there is an inducing path between two non-adjacent nodes x and y, then a nondirected edge x o-o y is
+     * added between them. In a PAG, x and y are adjacent if and only if there is an inducing path between x and y, so
+     * this is an error that should be fixed. It's possible the final orientation will orient it, but it's also possible
+     * that it will remain nondirected.
+     * 
            
+     * The final orientation is then done using the supplied FciOrient object, which should be configured to have the
+     * desired behavior.
+     * 
            
+     * As changes that are made above may imply further changes, the process is repeated until no further changes are
+     * made.
+     * 
            
+     * The end result of this repair process may not be a legal PAG if additional edges are oriented by knowledge or by

Subject: [PATCH 182/320] Update `Grasp` and `TeyssierScorer` constructor
 arguments

The `test` instance has been added as a constructor argument in both Grasp and TeyssierScorer classes in the LvLite.java file. Additionally, some changes related to MsepTest have been made in the LvLite.java under the oracle.pag package. Annotations in the LvLiteDsepFriendly.java have been commented out as part of this commit.

Subject: [PATCH 184/320] Update attribute names and improve parallel
 computations

Renamed 'equalityThreshold' attribute to 'allowableScoreDrop' across multiple files to better reflect its purpose. Also refactored 'removeExtraEdges' and 'tryRemovingEdge' methods to improve performance by leveraging parallel computations. Moreover, the creation of descendant models functionality within 'SessionEditorNode' was updated, replacing the 'SwingUtilities.invokeLater' approach with a new 'WatchedProcess' instance. All related parameters and documentation are updated accordingly.

Subject: [PATCH 185/320] Refactor edge removal methods in LvLite

Refactored methods in LvLite.java that handle the removal of extra edges. Now, it includes the handling for unshielded colliders for more precise edge elimination. Accompanying tests were commented out due to changes in these functions. Adjustment on other methods were made to accommodate these changes.

Subject: [PATCH 188/320] Refactor LvLite and related classes for clarity and
 performance; ensured edge specialization in the interface is done only for
 directed edges.

The LvLite and related classes' algorithm handling and edge rendering characteristics were optimized, improving overall performance. Edge distinction has been improved using solid and thick properties for different edge types, enhancing code readability. Removed unnecessary conditions concerning bookmarks in the TeyssierScorer class. Enabled the LvLiteDsepFriendly class and clarified its parameters.

Subject: [PATCH 189/320] Refactor LvLite class and update edge type
 documentation

Refined the LvLite class by removing unnecessary elements, enhancing parts related to paths and conditioning set, and incorporated performance time logging for BOSS and GRaSP algorithms in verbose mode. Updated the documentation for PAG edges to specify that markup properties apply to directed edges only. Also, standardized text changes were made in MarkovCheckEditor and test class.

Subject: [PATCH 190/320] Add 'knowledge' parameter to graph processing methods

The 'knowledge' parameter has been added to several graph processing methods such as 'repairFaultyPag', 'recallUnshieldedTriples' and few others across different classes. This was done to enable the ability to check if certain conditions are forbidden based on 'knowledge' during the graph repair and recall process.

Subject: [PATCH 191/320] Add option to remove extraneous variables in
 MarkovCheckEditor

An option has been added to the MarkovCheckEditor that allows for the removal of extraneous variables when d-separation holds. This new feature, controlled by a checkbox, is designed to form smaller conditioning sets. As part of these changes, extraneous variables logic has been further implemented in the MarkovCheck class.

Subject: [PATCH 192/320] Update parameter descriptions and add new option in
 conditioning set type

The method parameter descriptions in LvLite and GraphUtils classes have been updated for clarity. In the MarkovCheckEditor class, a new item "Parents(X) and Neighbors(X)"  has been added to the 'conditioningSetTypeJComboBox' component. This new entry corresponds to a new ConditioningSetType 'PARENTS_AND_NEIGHBORS'.

Subject: [PATCH 193/320] Remove LvLiteDsepFriendly class from the project

This commit removes the LvLiteDsepFriendly class from the project as it is no longer necessary. Other minor changes include updates to the allowable score drop in LvLite, making verbose output in GFci not mandatory, and adding a new test class for latent variable PAG algorithms.

Subject: [PATCH 194/320] Update LvLite and related classes

This update includes refactoring of the LvLite class and the removal of the LvLiteDsepFriendly class. Also, the option to produce verbose output in GFci is no longer mandatory. New test class added for latent variable PAG algorithms.

Subject: [PATCH 195/320] Update graph algorithm and remove unnecessary debug
 log

In this commit, several changes were made to the graph algorithm in various files, especially in classes SemGraph, LvLite and RegressionDataset. Pointless system.out calls used for debug log were removed. Some variables in LvLite were changed to improve the accuracy of the algorithm. Also, several redundant blocks of code were eliminated, increasing the simplicity and readability of the code. Meanwhile, a double-check method for DDP construct was added to ensure the fidelity of the construct.

Subject: [PATCH 196/320] Refactor LvLite algorithm and update GraphUtils

Significantly refactored LvLite algorithm for the Tetrad library. Added a new function to prevent the creation of almost cycles and improved the process of removing extra edges in a graph based upon specified conditions. Also, updated the GraphUtils function to handle directed cycles in the estimated PAG.

Subject: [PATCH 197/320] Add statistics for adjacencies in PAG graphs

This commit adds classes for calculating the number of genuine, induced, and covering adjacencies in Partial Ancestral Graphs (PAGs). Specific methods to determine induced and covering adjacencies were added in GraphUtils.java. These metrics can help in evaluating the discrepancies between the estimated and true PAGs.

Subject: [PATCH 198/320] Refactor collider addition logic in LvLite.java

The collider addition logic in LvLite.java has been refactored. A section of code has been commented out to optimize the process, and the nested for loops have been revised to prevent redundancy and improve execution efficiency. New conditions have been also added to prevent testing on the same set of nodes more than once.

Subject: [PATCH 199/320] Update SemBicScore parameter in TestCheckMarkov tests

All instances of the SemBicScore constructor within TestCheckMarkov have been updated. The second parameter has been changed from false to true to reflect a change in the expected default behavior of this class. This ensures tests are accurately reflecting the updated functionality of the SemBicScore class.

Subject: [PATCH 200/320] Refactor LvLite search, improve path handling, and
 enhance PAG adjustments

The LvLite search algorithm has been updated significantly for better performance and code readability. Notably, the score equality threshold has been renamed from "allowableScoreDrop" to "maxScoreDrop" to improve clarity. Also improved the handling of edge traversal in Paths.java by adding a check for directed edges. This prevents certain edge cases from causing issues in the execution of the search algorithm. Additionally, introduced adjustments in the post-processing of PAGs for enhanced accuracy. In some places, changes were made to enhance thread safety in multi-threaded applications. Finally, other minor code refactors are done for better code readability and efficient execution.

Subject: [PATCH 201/320] Refactor LvLite.java and add maxBlockingPathLength
 field

Code in LvLite.java has been restructured for optimal organization and readability. Additionally, a new field 'maxBlockingPathLength' has been introduced. This field represents the maximum length of blocking paths, providing an additional control parameter for the search algorithm.

Subject: [PATCH 202/320] Refactor LvLite and FciOrient classes for enhanced
 code optimization

The LvLite and FciOrient classes have been revamped. Unnecessary verbose logging and certain code documentation were removed, improving the readability of the code and reducing the cognitive load on the developers. This refactor also introduced the use of SepsetsGreedy and adjusted edge removal logic within the algorithms. The update should enhance the overall efficiency and performance of the application.

Subject: [PATCH 204/320] Update LvLite algorithm and related files

The commit incorporates a control for maximum separating set size in the LvLite algorithm and changes "tested" to "checked" for clarity. It has updated the documentation and related methods accordingly. Additionally, it includes synchronization for getChildren and getParents methods in EdgeListGraph and renames ALLOWABLE_SCORE_DROP to MAX_SCORE_DROP for consistency.

Subject: [PATCH 205/320] Rename and modify NumInducedAdjacenciesInPag to
 NumEdgeInEstInTrue

The implementation of the NumInducedAdjacenciesInPag class has been renamed to NumEdgeInEstInTrue to clarify the function of the class. This change is in line with the alteration in the logic of determining induced adjacency: instead of looking for adjacencies in the estimated graph but not in the true graph, the code now checks for adjacencies which are present in both the estimated and true graphs. Also, minor changes have been made in GridSearchEditor and NumCoveringAdjacenciesInPag class, adjusting the sequence of method calls and the abbreviation used respectively.

Subject: [PATCH 206/320] Refactor comparison process to use WatchedProcess

Moved the comparison and area update operations inside a WatchedProcess to run asynchronously. The original synchronous operations were commented out. The changes were applied to StatsListEditor and EdgewiseComparisonEditor classes. This refactoring helps avoid UI freezes, especially when dealing with large comparisons.

Subject: [PATCH 208/320] Refactor LvLite and BFci classes for clarity and
 performance

The LvLite class has been substantially revised to improve code readability and efficiency. Key changes include streamlining the tryRemovingEdge and tryAddingCollider methods, and renaming some methods and variables for representation clarity. Methods have also been documented. Similarly, BFci has been changed to use the SepsetsGreedy class for improved performance.

Subject: [PATCH 209/320] Refactor LvLite and update search methods

The LvLite class has been refactored to encompass modifications in search methods and other configurations for creating a PAG. New methods have been created to handle instances like 'BossSearch', 'GraspSearch', and 'FciOrient' in a more organized and cleaner way. Furthermore, an improvement with 'allPaths' method in the Paths class has been extended to limit the maximum number of paths. Lastly, the BFci and GraspFci classes were updated to use 'SepsetsMinP' instead of 'SepsetsGreedy'.

Subject: [PATCH 210/320] Refine wording and adjust parameters in LvLite class

This update includes modifications to the LvLite class that better clarify the description sentences. Changes include the improvement of comment wording for a clearer understanding. Also, the maximum value for the 'allPaths' function has been increased from 500 to 800 to provide greater search capabilities. Multiple small improvements to grammar and wording have been made for enhancing readabilty and understanding.

Subject: [PATCH 211/320] Refine LvLite algorithm and documentation

The LvLite algorithm has been enriched with latent variables along with BOSS or GRaSP algorithm for initial CPDAG. The algorithm now includes scoring steps for inferring unshielded colliders in the graph, and a testing step to eliminate extra edges. Additionally, detailed information and comments have been added to the code to enhance understanding of this method and its capabilities.

Subject: [PATCH 215/320] Refactor LvLite and update FciOrient; add tucking and
 testing flags

The LvLite class has been refactored to improve the efficiency of the overall algorithm. A number of additions and modifications were made to improve existing functions and add new ones. The FciOrient class was also updated to correct potential issues with path length. New options were introduced to allow control over the tucking and testing stages in the search algorithm.

Subject: [PATCH 216/320] Refactor code for better handling of directed acyclic
 graphs.

The commit includes updates to the sepset generation code and path traversal logic. The sepsets are now based on ancestors instead of tests. In path traversal, ancestor considerations have been added for better path generation. The code terminology has also been standardized to "DAG" for directed acyclic graphs.

Subject: [PATCH 217/320] Refined LvLite algorithm and updated graph statistics

The LvLite algorithm was refined with the addition of extra edge removal steps and further tuning parameter options. New statistics, including the number of tails in the estimated graph and the ratio of implied orientations to edges in unshielded colliders, were also introduced. Files and paths in the DemixerMMLKun.java were updated as well.

Subject: [PATCH 218/320] Remove unused checkTucked2 method and comments

The checkTucked2 method in LvLite.java was deleted, as it is no longer necessary. Some redundant comment lines were also removed in the process. This cleanup helps to maintain a less cluttered and more readable code base.

Subject: [PATCH 219/320] Refactor `FciOrient` for better path tracking
 mechanism

Changes have been made to `FciOrient` to improve the mechanism for tracking paths within the code. Previously, `LinkedList V` used to track the nodes but has now been replaced with a `HashSet` to eliminate duplicates and improve performance. A map (`previous`) has also been introduced to keep track of the previous node for each node, allowing proper reconstruction of the path.

Subject: [PATCH 221/320] Refactor FciOrient configuration and adjust usages

To simplify the configuration of the FciOrient class, a helper method was added to carry out the configuration using default and special values. The usages of FciOrient across all applicable classes were adjusted to employ these new methods. Minor edits were also made to satisfy the respect of encapsulation rules for the SepsetProducer interface across various classes.

Subject: [PATCH 222/320] Refactor FciOrient method and update classes

Methods have been updated in the FciOrient class to better manage knowledge and verbosity. This included changing calls of doFinalOrientation() to finalOrientation() throughout multiple classes. Adjustments were also made to ensure the IndependenceTest is correctly configured. Some default settings were changed in the LvLite class. There were also modifications towards the getters and setters, specifically setGraph(), across other classes for overall improvements in the program's functionality and clarity.

Methods across different classes have been updated to return Set and Set> instead of List and List>. This change ensures that duplicated Edge or List instances are not returned by these methods, providing cleaner and concise results to the client code. Classes affected include Graph, EdgeListGraph, and various classes in the 'search' package.

Subject: [PATCH 226/320] Change methods to return Set instead of List

Methods across different classes have been updated to return Set and Set> instead of List and List>. This change ensures that duplicated Edge or List instances are not returned by these methods, providing cleaner and concise results to the client code. Classes affected include Graph, EdgeListGraph, and various classes in the 'search' package.

Subject: [PATCH 227/320] This version of LV-Lite is regularly passing a Markov
 check.

Refactor LvLite algorithm and associated files

The LvLite algorithm has been refactored to simplify the code and improve readability. Unnecessary features, such as the EXTRA_EDGE_REMOVAL_STEP, which added complexity to the code, have been removed. The code related to edge processing and graph generation has also been significantly modified to be more efficient and provide cleaner orientation of the graph. This revision ensures the orientation process is more streamlined and less prone to errors.

Subject: [PATCH 228/320] Refactor code across multiple files and methods

This commit includes a significant refactor of several Java files. Major changes include the removal of large sections of code from LvLite.java and SessionEditorNode.java, along with changes to GraphUtils.java. The removed sections mostly involve complicated logic or unused commented blocks. Updated methods like "launchEditorVisit()" and "repairFaultyPag()" have been simplified and become more straightforward.

Subject: [PATCH 231/320] Refactor graph manipulation in search algorithms

Adjusted the initialization and manipulation of Graph objects within different search algorithms to improve structure and efficiency. Modified handling of nodes and edges with a focus on improving separation sets and path blocking. This also includes enhancements to how faulty PAGs are repaired to handle edge cases and improve robustness. Updated related GUI elements to synchronize with these changes.

Subject: [PATCH 232/320] Add option to skip final orientation step in
 algorithms

Adds an option and corresponding setter, 'ablationLeaveOutFinalOrientation', to several search algorithms which can be used to skip the final orientation step of these algorithms if desired. The new option is also documented in the index.html manual.

Subject: [PATCH 233/320] Remove redundant 'repairFaultyPag' method

The 'repairFaultyPag' method in the 'LvLite' class has been removed. It had become redundant in the codebase as it wasn't being used or called anywhere else. This is part of a cleanup process to eliminate unutilized code and improve the overall maintainability of the codebase.

Subject: [PATCH 234/320] Add new SepsetFinder class and refactor related
 classes

A new class, SepsetFinder, has been added. This class is responsible for finding a Sepset between two given nodes, which is a complex task. Multiple methods that were originally located in the Paths class have been moved to the new SepsetFinder class. This was done to improve modularity and maintainability by separating concerns. Code in the FciOrient class has been updated to use the new class.

Subject: [PATCH 235/320] Refactor Sepset classes for efficiency

The SepsetsMinP, SepsetsMaxP, and SepsetsGreedy classes have been significantly refactored. The 'extraSepsets' parameters were removed and a more efficient approach was adopted to find the separator set without the need for complex calculations. The debugging verbosity was also incorporated through a new 'verbose' flag. Additionally, the method of finding the Directed Acyclic Graph in SepsetsMinP and SepsetsMaxP was adjusted. Unnecessary imports were removed, and comments were improved for clarity.

Subject: [PATCH 236/320] Refactor SepsetsGreedy to improve performance

The 'SepsetsGreedy' class has been extensively modified to improve its performance. It has been refactored to use the 'SepsetFinder.getSepsetContainingGreedy' method instead of its private method, 'getSepsetGreedyContaining', which has been removed. Additionally, the name of the class occurs within comments has been updated from 'SepsetsGreedy' to simply 'Sepsets'. Other classes in the system have been updated to accommodate these changes.

Subject: [PATCH 237/320] Add selection of sepset finder method in SpFci and
 BFci

Added a configuration parameter 'sepsetFinderMethod' in SpFci and BFci classes to allow users to choose the method for finding sepsets - whether it's greedy, min-p or max-p.
This allows greater flexibility and control over the performance of the algorithms. The parameter is also reflected in the documentation manually.

Subject: [PATCH 240/320] Add depth parameter to sepset finding functions

The 'depth' parameter has been added as an argument to 'getSepSet' functions in multiple files to provide more control over search depth. The detailed code changes also extend this parameter to 'isUnshieldedCollider' and 'getSepSetContaining' functions. These changes are based on the observation that including 'depth' in the sepset functions provides the possibility of specifying the maximum number of conditioning variables for independence tests, thus improving the flexibility and efficiency of the algorithm.

Subject: [PATCH 241/320] Refactor sepset path blocking method in SepsetFinder

The method `getSepsetPathBlocking2` has been refactored for clarity and renamed to `getSepsetPathBlockingOutOf` in the `SepsetFinder` class. The update comprises changes in the method signature and logic to correctly compute separation sets for a given pair of nodes in a graph. Additionally, the method calls in `LvLite`, `FciOrient`, and `TestSepsetMethods` have been updated to reflect the refactored method name.

Subject: [PATCH 242/320] Refactor SepsetFinder and related methods

The SepsetFinder method has been renamed to `getSepsetPathBlockingXtoY` and refactored, along with related methods in LvLite, FciOrient, and Paths classes. Some parameters have been removed and method implementations have been updated. The changes are made to bring more clarity and limit the number of unnecessary parameters in the methods. The test class `TestSepsetMethods` has also been updated to reflect these changes.

Subject: [PATCH 243/320] Refactor LvLite and SepsetFinder and enhance code
 consistency

This commit refactors the LvLite and SepsetFinder classes to ensure consistency and clarity of the code. Renamed 'noncolliders' to a more understandable variable name 'conditioningSet'. Also, removed commented out code and redundant checks in SepsetFinder for cleaner code. The consistency is seen in LvLite, where it is no longer necessary to call SepsetFinder with an unused parameter, improving the method calling process.

Subject: [PATCH 244/320] Refactor sepset finder and remove unnecessary code

Simplified code in SepsetFinder.java by removing inactive (commented out) sections and some unnecessary line breaks. Also, augmented the javadoc for several methods to prominently include more detailed explanation of their functionality and their parameters.

Subject: [PATCH 245/320] Refactor SepsetFinder and TestSepsetMethods

The SepsetFinder's handling of noncollider addition has been adjusted to only include if z1 is equal to x, improving the method's efficiency. Refactored the TestSepsetMethods class, making method signatures and inner workings more straightforward. Removed clutter and redundant comments to enhance clarity.

Subject: [PATCH 246/320] Update method name in output message

The output message of the timing function was updated to reflect the correct method name. Instead of "getSepsetPathBlockingXtoY", the message now properly refers to the "getSepsetPathBlockingOutOfXOrY" method.

Subject: [PATCH 247/320] Update test parameters in SepsetMethods test cases

The number of nodes and edges in the test1() and test6() methods within TestSepsetMethods have been reduced from 50 to 20 and 100 to 40 respectively. This change is to make the tests more manageable and less resource-intensive.

Subject: [PATCH 248/320] Refactor SepsetFinder methods and update tests

Refactored methods in the SepsetFinder class to enhance their functionality. This refactor includes creating separate variables for 'sepsetPathBlockingOutOfX' and 'sepsetPathBlockingOutOfY'. The 'getSepsetPathBlockingOutOfXOrY' method now returns 'sepsetPathBlockingOutOfX' or 'sepsetPathBlockingOutOfY' based on which one is not null, instead of checking node adjacency sizes. These changes have been reflected in the corresponding test cases in the TestSepsetMethods class.

Subject: [PATCH 249/320] Add new functions for graph conversion and update
 existing ones

Several improvements and new capabilities were added to the DagToPag classes. A function for converting a graph from DAG to MAG format was added, including steps for adding adjacency based on inducing paths, finding all ancestor relations, and using these relations to set up graph endpoints. The 'calcAdjacencyGraph' function was modified to only consider measured nodes. The explanatory comments for these functions, and for the adjacency search in 'DagToPag.convert()', were updated for clarity. At the same time, redundant conditions checking if nodes were adjacent were removed. Several other minor corrections and improvements were also included.

Subject: [PATCH 250/320] Update search methods and remove tucking steps

Updated search methods in 'LvLite.java' to use a different approach. The 'tucking steps' in the method have been commented out and a new D-SEP method has been added 'SepsetFinder.java'. Refactored related classes to adapt to the new approach accordingly.

Subject: [PATCH 251/320] Refactor separation set logic and improve sepset
 handling

Refactor code to use MAG instead of DAG for sepset calculations. Introduce SepsetFinder methods for more precise and context-aware sepset discovery. Adjust logging and function signatures to match updated logic.

Subject: [PATCH 252/320] Remove discriminating path rules from DAG to PAG
 conversions

Eliminated the discriminating path tail and collider rules from the DAG to PAG conversion classes. This refactoring simplifies the algorithms by removing unnecessary configuration options. All related methods and variable declarations have been cleaned up accordingly.

Subject: [PATCH 253/320] Enhance D-SEP computation for MAGs and IPGs

Improved the D-SEP computation to support both maximal ancestral graphs (MAGs) and inducing path graphs (IPGs). Added detailed documentation and a new non-reachability style method for determining D-SEP. Updated relevant classes to integrate these enhancements.

Subject: [PATCH 255/320] Refactor and streamline LvLite and related classes

Converted `doubleCheckDiscriminatinPathConstruct` method to return a boolean instead of throwing exceptions. Removed unused private variables and methods related to score drop and tucking. Introduced `AlmostCycleRemover` to manage cycle-related operations. Simplified logic in `LvLite.java`, `FciOrientDataExaminationStrategyTestBased.java`, and `GraphUtils.java` for clarity and improved maintainability.

Subject: [PATCH 257/320] Refactor LvLite orientation methods and improve cycle
 removal

Refactored the LvLite class by extracting orientation and cycle removal logic into new methods. This change aims to enhance code readability and maintainability. Additionally, integrated AlmostCycleRemover with finalLvliteOrientation for cleaner cycle removals.

Subject: [PATCH 258/320] Refactor cycle-removal logic and cleanup LvLite class

Simplified the cycle-removal process by eliminating redundant methods from `AlmostCycleRemover` and moving key functionalities directly into LvLite and GraphUtils. This refactor enhances code maintainability and readability by centralizing related logic and removing unnecessary complexity. As a result, `AlmostCycleRemover` class is no longer required and has been removed. The changes also include better organization and documentation within the affected methods to facilitate easier understanding and further improvements.

-/**
- * A class for heuristically removing almost cycles from a PAG to avoid unfaithfulness in an estimated PAG. An almost
- * cycle is a path x ~~> y where x <-> y. Bidirected edge semantics for PAGs require that there be no almost
- * directed cycles, though LV algorithms may produce them.
- * 
            
- * This class is meant to be incorporated into a latent variable algorithm and used to remove almost cycles from the
- * graph in the final step.
- * 
            
- * The method works by identifying almost cyclic paths for x <-> y where there is a semidirected path from x to y
- * in the estimated PAG and then removing all unshielded collider orientations into x for these. This removes the need
- * to orient a collider at x for these edges, and so removes the need to orient a path out of x to y. Almost directed
- * paths are symptomatic of unfaithfulness in the data (implying dependencies that should not exist if the output is a
- * faithful PAG), so this is a reasonable heuristic.

+/**
+ * A class for heuristically removing almost cycles from a PAG to avoid unfaithfulness in an estimated PAG. An almost
+ * cycle is a path x ~~> y where x <-> y. Bidirected edge semantics for PAGs require that there be no almost
+ * directed cycles, though LV algorithms may produce them.
+ * 
            
+ * This class is meant to be incorporated into a latent variable algorithm and used to remove almost cycles from the
+ * graph in the final step.
+ * 
            
+ * The method works by identifying almost cyclic paths for x <-> y where there is a semidirected path from x to y
+ * in the estimated PAG and then removing all unshielded collider orientations into x for these. This removes the need
+ * to orient a collider at x for these edges, and so removes the need to orient a path out of x to y. Almost directed
+ * paths are symptomatic of unfaithfulness in the data (implying dependencies that should not exist if the output is a
+ * faithful PAG), so this is a reasonable heuristic.

Subject: [PATCH 260/320] Disable cycle removal and add allPathsOutOf3 method

Commented out the cycle removal and reorientation logic in LvLite.java for possible debugging. Introduced the allPathsOutOf3 method in SepsetFinder.java to enhance pathfinding capabilities, including checks for m-connecting paths.

Subject: [PATCH 261/320] Refactor sepset path blocking logic and update tests.

Replaced and optimized logic for sepset path blocking from nodes X to Y across different components. Added new methods to handle sepset calculations more efficiently. Adjusted and commented out related test cases to reflect these changes.

Subject: [PATCH 262/320] Update path blocking methods and clean up comments

Revised path blocking algorithms for better performance and code clarity. Switched from "mag" to "pag" in relevant sections and added handling for selection bias. Also, removed outdated comments and unused methods, and reformatted code documentation for consistency.

Subject: [PATCH 263/320] Refactor LvLite to use 'dag' instead of 'cpdag'

Replaced all instances of 'cpdag' with 'dag' to maintain consistency in variable naming. Removed unused tucking-related code and comments. Enhanced `SepsetFinder.getSepsetPathBlockingOutOfX` with a blacklist parameter, modified log messages, and cleaned up redundant path blocking methods.

Subject: [PATCH 264/320] Update FciOrient initialization in LvLite class

Added the setCompleteRuleSetUsed configuration to the FciOrient instance during initialization. This ensures that the complete rule set is consistently applied throughout the orientation process in the LvLite class. Removed an unnecessary variable declaration for code clarity.

Subject: [PATCH 273/320] Update LV-Lite parallel execution and add timeout
 handling

Changed `extraEdgeRemovalStyle` to parallel for enhanced performance and added sorting of edges based on adjacency count. Introduced a 300ms timeout for future tasks in `SepsetFinder` to handle potential delays. Also, added a new utility class `DiscriminatingPath` for representing discriminating paths in graphs.

Subject: [PATCH 275/320] Refactor SepsetFinder and update
 discriminatingPathOrient

Adjusted the parameters for SepsetFinder calls to use -1 instead of 300 for clarity and consistency. Also, extended discriminatingPathOrient method to handle discriminatingPaths set, facilitating the use of discriminating paths across ruleR4 executions.

Subject: [PATCH 276/320] Introduce timeout for extra edge removals and
 FciOrient steps

Added a configurable timeout mechanism for the extra edge removal and FciOrient steps to improve performance and prevent long-running tasks. Introduced new methods to handle timeouts and updated related classes to support these changes.

Subject: [PATCH 277/320] Refactor timeout handling and synchronize methods

Moved the `runWithTimeout` method to `GraphSearchUtils` and synchronized methods `setEndpoint` and `doDiscriminatingPathOrientation`. These changes enhance code modularity and thread safety. Additionally, removed debug prints and improved logging consistency.

Subject: [PATCH 278/320] Implement Pair return type for path orientation
 methods

Refactor doDiscriminatingPathOrientation methods to return Pair, improving clarity by including both the discriminating path and a boolean result. Adjust associated calls and documentations to accommodate the new return type, ensuring backward compatibility and code readability. Also, added a test timeout parameter to applicable methods.

Subject: [PATCH 279/320] Implement support for allowed colliders in FCI
 algorithms

Added the ability to set allowed colliders for FCI orientation strategies to prevent certain unshielded colliders from being modified. Adjusted methods in FciOrient, FciOrientDataExaminationStrategy, and related classes to utilize allowed colliders for more precise graph orientation operations.

Subject: [PATCH 280/320] Refactor FciOrient and LvLite for consistency

Refactor method names and parameters for clarity and consistency in `FciOrient` and `LvLite` classes. Added methods to manage initial allowed colliders for improved collider handling. Cleaned up deprecated and redundant code.

Subject: [PATCH 281/320] Refactor logging for better readability and context

Moved and added additional logging statements to improve clarity and provide better context while handling almost cycles and unshielded triples in LvLite.java. Added start and end log messages for the discriminating path orientation process in FciOrient.java.

Subject: [PATCH 285/320] Refactor graph pathfinding to use Dijkstra's
 algorithm

Replaced non-directed edge addition with bidirected edge addition in GraphUtils as per Zhang 2008. Implemented a new Dijkstra algorithm in Dijkstra.java to improve performance in FciOrient, avoiding potential hangs on large graphs by finding uncovered paths.

Subject: [PATCH 286/320] Add "Make All Edges Nondirected" functionality

Implemented a new static method `nondirectedGraph` in `GraphUtils` to convert graphs to have nondirected edges. Added a new class `AllEdgesNondirectedWrapper` and made necessary updates to configuration files to support the new functionality in both production and development environments.

Subject: [PATCH 287/320] Add "Make All Edges Nondirected" functionality

Implemented a new static method `nondirectedGraph` in `GraphUtils` to convert graphs to have nondirected edges. Added a new class `AllEdgesNondirectedWrapper` and made necessary updates to configuration files to support the new functionality in both production and development environments.

Subject: [PATCH 288/320] Improve Dijkstra implementations for FciOrient and
 Graph handling

Refactor FciOrient class to utilize a precomputed Dijkstra graph.
Implement `traverseNondirected` method and improve handling
of graph traversal in Dijkstra. Add verbose flag to Fci class for
debugging and adjust unit tests to reflect changes.

Subject: [PATCH 289/320] Rename Dijkstra utility to FciOrientDijkstra for
 specialization

Renamed the Dijkstra utility class to FciOrientDijkstra to reflect its specific application in FciOrient rules R5, R9, and R10. Updated all references and implemented a more specialized Dijkstra's algorithm tailored for FCI orientation-related tasks in tetrad-lib.

Subject: [PATCH 290/320] Rename Dijkstra utility to FciOrientDijkstra for
 specialization

Renamed the Dijkstra utility class to FciOrientDijkstra to reflect its specific application in FciOrient rules R5, R9, and R10. Updated all references and implemented a more specialized Dijkstra's algorithm tailored for FCI orientation-related tasks in tetrad-lib.

Subject: [PATCH 291/320] Rename Dijkstra utility to FciOrientDijkstra for
 specialization

Renamed the Dijkstra utility class to FciOrientDijkstra to reflect its specific application in FciOrient rules R5, R9, and R10. Updated all references and implemented a more specialized Dijkstra's algorithm tailored for FCI orientation-related tasks in tetrad-lib.

+/**
+ * A modified implementation of Dijkstra's shortest path algorithm for the R5 and R9 rules from Zhang, J. (2008), On the
+ * completeness of orientation rules for causal discovery in the presence of latent confounders and selection bias,
+ * Artificial Intelligence, 172(16-17), 1873-1896. These are rules that involve finding uncovered paths of various sorts
+ * in a graph; we use a modificiation of Dejkstra as a fast implementation of that requirement suitable for large
+ * graphs.
+ * 
            
+ * We report distances as total weights along the shortest path from the start node to the y node, where by default the
+ * weight of each edge is 1. We report unreachable nodes as at a distance of Integer.MAX_VALUE. Edges in the graph are
+ * dynamically calculated by the algorithm using two methods--looking for o-o edges only, suitable for the R5 rule, and
+ * looking for edges along potentially directed paths (i.e., semidirected paths), suitable for the R9 rule. The end node
+ * is used to stop the algorithm once that node has been visited, so that a shortest path has been found.
+ * 
            
+ * The algorithm is constrained to avoid certain paths. The start *-* end edge itself and start *-* z *-* end paths are
+ * avoided, to avoid length 1 or length 2 paths. Also, covered triples, z *-* r *-* w, z *-* w, are avoided to implement
+ * the constraint that only uncovered paths are considered. Coverings of end *-* start *-* z and start *-* end *-* w are
+ * also avoided, as specified for R5 and R9.

Subject: [PATCH 293/320] Rename R4Strategy to R0R4Strategy and update related
 references.

Renamed `R4Strategy` to `R0R4Strategy` to reflect its responsibility for both R0 and R4 rules, and updated all corresponding references in the codebase. Updated documentation to clarify the usage and functionality related to R0 and R4 orientation rules.

Subject: [PATCH 295/320] Add handling for partially oriented edges and
 refactor rules

Implemented logic to handle 'o--' and '--o' edge specifications in `GraphUtils`. Refactored FCI orientation rules including rules R6 and R7 for better clarity and efficiency. Updated test cases in `TestFci` to reflect changes in edge orientation logic.

Subject: [PATCH 296/320] Refactor GraphUtils handling and adjust FciOrient
 signature

Enhanced `GraphUtils` to handle new edge types and updated the `Counts` array size to accommodate these changes. Additionally, modified the method signature of `FciOrient.orient` to remove an unnecessary return statement, improving the method's clarity and correctness.

 /**
- * Represents a discriminating path in a graph.
+ * Represents a discriminating path; the orientation for the nodes in a Directed Acyclic Graph (DAG) based on the
+ * Discriminating Path Rule. The path is <X,...,W, V, Y>, with nodes between X and V colliders along the path and
+ * parents of Y (Zhang 2008). The question is whether there's a sepset S such that X _||_ Y | S, and whether S contains
+ * V or not. If it does, then <X, V, Y> is a noncollider; otherwise, it is a collider. This is Zhang's rule R4,
+ * discriminating paths.
+ * 
            
+ * Pictorially:
+ * 
            + *      The triangles that must be oriented this way (won't be done by another rule) all look like the ones below, where
+ *      the dots colliders between X and V with each node on the path (except X) a parent of Y.
+ *
+ *               V
+ *              xo           x is either an arrowhead or a circle
+ *             /  \
+ *            v    v
+ *      X.....W--->Y

- * 
            Adapts FciOrient for the SvarFCI algorithm. The main difference is that if an edge is orient,
- * it will also orient all homologous edges to preserve the time-repeating structure assumed by SvarFCI. Based on (but
- * not identicial to) code by Entner and Hoyer for their 2010 paper. Modified by DMalinsky 4/20/2016.

- * 
            This class is configured to respect knowledge of forbidden and required
- * edges, including knowledge of temporal tiers.

Subject: [PATCH 303/320] Refactor DiscriminatingPath and related
 classes/methods.

Updated the `DiscriminatingPath` class to include additional documentation, rename methods for clarity, and improve path checking logic. Enhanced comments and checks in relevant methods in `FciOrient`, `DagToPag`, and `R0R4StrategyTestBased` to ensure correctness and readability. Adjusted test cases in `TestFci` to align with new path orientation rules.

Subject: [PATCH 307/320] Conditionally log messages based on verbosity

Wrapped all logging statements with a verbosity check (`if (verbose)`) to ensure logs are generated only when the `verbose` flag is enabled. This reduces unnecessary logging and improves performance in non-verbose mode. The change affects multiple sections in the `LvLite.java` file, enhancing overall log management.

Subject: [PATCH 309/320] Add Javadoc to various classes and methods

Added Javadoc comments to several classes and methods across multiple files, including DefaultSetEndpointStrategy, SetEndpointStrategy, R5R9Dijkstra, GraphSearchUtils, SvarSetEndpointStrategy, R0R4Strategy, FciOrientDijkstra, Paths, and Edges.

Subject: [PATCH 311/320] Remove redundant ablation parameter and add logging

Eliminated the `ABLATION_LEAVE_OUT_FINAL_ORIENTATION` parameter as it is no longer used, simplifying the `SpFci` algorithm setup. Added logging to mark the number of available processors during parallel execution in `MarkovCheck`, enhancing debugging capabilities.

Subject: [PATCH 312/320] Refactor FCI to handle unshielded triples and repair
 faulty PAGs

Refactored FCI search algorithms (Fci, SvarFci, SpFci, GraspFci) to manage unshielded triples for rule R0 orientation. Added repairFaultyPag method to correct faulty PAGs using unshielded triples, inducing paths, and final orientations. Updated HTML documentation to reflect new parameter descriptions and default values.

-     * this is an error that should be fixed. It's possible the final orientation will orient it, but it's also possible
-     * that it will remain nondirected.
+     * Second, if there is an inducing path between two non-adjacent nodes x and y, then an edge x *-*.y is added.
+     * Arrows are included at x and y if including them prevents almost cycles.

Subject: [PATCH 316/320] Refactor cycle resolution and add setter methods in
 GFci

Refactor `resolveAlmostCycles1` by removing the redundant `anyChange` parameter and clean up commented code. Add new setter methods in `GFci` for discriminating path tail and collider rules, improving configurability.

            Description
            
+
+    
            
+        
             LV-Lite starts with BOSS or GRaSP and get a valid order and a DAG/CPDAG. It sets the initial state of the
+            estimted PAG to this CPDAG and orients as o-o and then copy all of the unshielded colliders from the CPDAG
+            to the PAG. It then performs a testing modified from the step in GFCI that is more efficient. In GFCI, an
+            edge x *-* y is removed from the graph is there is a subset S of adj(x) \ {y} or adj(y) \ {x} such that x
+            _||_ y | S. For LV-Lite we instead search outward from x for a set S using a novel procedure that blocks all
+            existing paths in the estimated PAG either unconditionally or conditionally. Bounds may be placed on the
+            lengths of the blocked paths to consider and the depth (maximum |S|). We also allow bounds on the time
+            spent on any testing step. As edges are removed in this way, any additional colliders are oriented given
+            these sepsets S. We then run the final FCI orientation rules, where for the discriminating path rule we use
+            the same "out of x" sepset finding idea. We optionally allow the user to request that a legal PAG be
+            returned using a novel procedure; this guarantee has been extended to all latent variable algorithms in
+            Tetrad that return partial ancestral graphs (PAGs).
+        
            
+
+        
            LV-Lite, along with BFCI, can produce highly accurate models in simulation. LV-Lite, in particular, is highly
+            scalable. A paper describing BFCI and LV-Lite in more detail is planned. We make both BFCI and LV-Lite
+            non-experimental for this version since requests have been made to use them.
            
+        
            
+
+        
            Note: If one wants to analyze time series data using this algorithm, one may set the time lag parameter to a
+            value greater than 0, which will automatically apply the time lag transform. The same goes for any algorithm
+            that has this parameter available in the interface.

Subject: [PATCH 318/320] Switch version from 7.6.5-SNAPSHOT to 7.6.5

Updated the version in multiple POM files to move from the 7.6.5-SNAPSHOT development version to the 7.6.5 release version. This change ensures the project dependencies align with the stable release. Also, improved the Javadoc for the `ruleR0` method in `FciOrient.java` for better clarity.

Subject: [PATCH 320/320] Change Java compatibility from 21 to 17

Updated the Maven configuration across multiple POM files to change the Java source and target versions from 21 to 17. This ensures compatibility with environments requiring Java 17, and updates relevant plugin configurations accordingly.
