Code from the paper "Lifted Successor Generation using Query Optimization Techniques"

Note: In the paper, the description of the successor generator using Yannakakis' algorithm is not correct if there are inequalities in the precondition. To correct this, we can consider free variables occurring in inequalities as distinguished variables. The conclusions drawn from the experimental results are not affected by this change.

Source code used in the experiments from the paper "Lifted Successor Generation using Query Optimization Techniques" (Corrêa et al. ICAPS 2020). The zip file contains the source code directory, a Python script to run the lifted planner, and a README file explaining the usage of the planner.
