Systems

Here, you can find most of the systems developed so far by the group. All of them are based on Prolog (usually Eclipse, SWI, LPA, and Quintus.)
  • Golog: A high-level agent programming language.

    An interpreter in SWI Prolog can be found here.
    An interpreter in ECLIPSE Prolog can be found here.
    More code related with Golog can be found in Reiter’s book Knowledge in Action: Logical Foundations for Specifying and Implementing Dynamical Systems. Click here to go to the book’s homepage.

  • ConGolog: Concurrent Golog.

    ConGolog incorporates concurrency, interrupts, and exogenous actions into Golog. Hence, it allows the design of more flexible controllers for agents living in complex scenarios.
    If you want to get the corresponding code, please contact Yves Lespérance.

  • IndiGolog: Incremental Deterministic (Con)Golog.

    IndiGolog is a high-level programming language where programs are executed incrementally to allow for interleaved action, planning, sensing, and exogenous events. IndiGolog provides a practical framework for real robots that must react to the environment and continuously gather new information from it. To account for planning, IndiGolog provides a local lookahead mechanism with a new language construct called the search operator.
    Indigolog is currently in “alpha” stage. You can download the latest version via svn using the following command:
    svn co https://indigolog.svn.sourceforge.net/svnroot/indigolog indigolog
    You can get an earlier version (linux-0.5alpha1) here.

  • LeGolog: Lego MINDSTORM in ConGolog.

    LeGolog is a complete agent architecture implementation in Prolog for running IndiGolog high-level programs in Lego MINDSTORM robots.

  • Planning with Loops: An iterative planner based on Situation Calculus.
