PyGAD 2.17.0

Release Date: 8 July 2022

  1. An issue is solved when the gene_space parameter is given a fixed value. e.g. gene_space=[range(5), 4]. The second gene's value is static (4) which causes an exception.
  2. Fixed the issue where the allow_duplicate_genes parameter did not work when mutation is disabled (i.e. mutation_type=None). This is by checking for duplicates after crossover directly. #39
  3. Solve an issue in the tournament_selection() method as the indices of the selected parents were incorrect. #89
  4. Reuse the fitness values of the previously explored solutions rather than recalculating them. This feature only works if save_solutions=True.
  5. Parallel processing is supported. This is by the introduction of a new parameter named parallel_processing in the constructor of the pygad.GA class. Thanks to [@windowshopr](https://github.com/windowshopr) for opening the issue [#78](#78) at GitHub. Check the [Parallel Processing in PyGAD](https://pygad.readthedocs.io/en/latest/README_pygad_ReadTheDocs.html#parallel-processing-in-pygad) section for more information and examples.
