Benchmarks for HTN Planning

• Benchmarks used in the International Planning Competitions (IPCs):

  • IPC 2023 benchmarks described in HDDL. Note that these are basically the 2020 benchmarks. Per track (total and partial order), 2 new domains were added. (I am not aware whether additional problem instances for 2020 domains were added.)
  • IPC 2020 benchmarks described in HDDL. The webpage of the IPC 2020 also offers a few simple test case benchmarks to test your planner and parser.

• Additional HTN domains described in HDDL. Those were collected when organizing the IPC 2020, but were not selected. The repository was also extended afterwards, but not significantly. Please contact Gregor Behnke and Pascal Bercher if you'd like to add your domain(s) here as well.

• FOND HTN domains. This benchmark set contains seven (acyclic) HTN domains, where actions have non-deterministic effects. Based on HDDL, but extended by a new one-of keyword to express problems for Fully Observable Non-Deterministic (FOND) planning. Kindly provided by Mohammad Yousefi.

• Flawed HTN domains. These domains or problems got deliberately infused with modeling errors to test your parser. Contains problems modeled in HDDL and PDDL. Maintained by Pascal Bercher.
