DALI

DALI Multi Agent Systems Framework

DALI is a meta interpreter built on top of Sicstus Prolog (R) (at the moment).

Installation

DALI is built upon the SICStus Prolog interpreter, for which you a need a valid license. You may use any latest SICStus version at your own risk, but DALI has been tested to work reasonably well with the 4.6.0 version.

Also some OS-specific instructions:

OS X & Linux:

You can download DALI and test it by running an example DALI MAS:

git clone https://github.com/AAAI-DISIM-UnivAQ/DALI.git
cd DALI/Examples/advanced
bash startmas.sh

     You will see different windows opening:

•      Prolog LINDA server (active_server_wi.pl)
•      Prolog FIPA client (active_user_wi.pl)
•      1 instance of DALI metaintepreter for each agent (active_dali_wi.pl)

Windows:

You can download DALI from https://github.com/AAAI-DISIM-UnivAQ/DALI.git.

• Unzip the repository, go to the folder "DALI/Examples/basic", and test if DALI works by duble clicking "startmas.bat" file (this will launch an example DALI MAS).
  
       You will see different windows opening:
•      Prolog LINDA server (active_server_wi.pl)
•      Prolog FIPA client (active_user_wi.pl)
•      1 instance of DALI metaintepreter for each agent (active_dali_wi.pl)

Usage example

You can find some examples into the Example folder, where examples are divided into 3 subfolders:

• basic: aimed at basic Windows-based setup, no agent types, every agent living in a separated sicstus window.
• advanced: more complex, aimed at Unix-like based environment, with agent type, instances, each agent living in a separated xterm console.
• more: MAS examples derived from our students projects.

Development setup

To create a new DALI MAS, you can use an example as a boilerplate:

1. Create a folder to contain your project, for example let's call it "projectFolder"
2. Copy the folder "DALI/src" into "projectFolder"
3. In "projectFolder", create a folder that will contain your DALI app, for example let's call it "DALIappFolder"
4. Copy the content of "DALI/Examples/advanced" folder in "projectFolder/DALIappFolder"
5. Rewrite the files contained in "projectFolder/DALIappFolder/mas/instances" and in "projectFolder/DALIappFolder/mas/instances" in a proper way (see DALI documentation), in order to create your DALI MAS.
6. Open the "startmas" file and change the following variables according to your paths:

• sicstus_home: The SICStus prolog path
• main_home: # The "projectFolder" path, in relation to the "startmas" file position (in this example it is "..")
• dali_home: # The "projectFolder/src" folder path, in relation to the "startmas" file position (in this example it is "../src")
• conf_dir: # The "projectFolder/conf" folder path, in relation to the "startmas" file position (in this example it is "conf")
