Freelunch is an open-source planning system written in Java. It takes input in the multivalued SAS+ format, which can be obtained from PDDL by the Fast Downward translation tool. Freelunch also provides a Java API to makeits use in Java applications convenient. The philosophy of Freelunch is to first find a plan of arbitrary quality and then improve it using post planning optimization techniques. Several algorithms are implemented in Freelunch, many of them are based on translation of planning problems into satisfiability (SAT) and using a SAT solver.

Support

Freelunch has not been tested with eviscerator yet. Freelunch is designed for classical domains and so most likely does not support temporal numeric planning.
