Infrastructure

The competition experiments run on hardware provided by the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC) at the Czech Technical University in Prague. We thank CIIRC for providing the evaluation infrastructure.

Tools and Advice

We thank Gregor Behnke for the code his tools contribute to the competition pipeline: parsing, grounding and plan verification built around the PANDA framework, on which previous HTN IPC editions also relied. He also shared his experience from organizing HTN IPC 2020 and 2023, and answered many of our questions.

Previous Editions

HTN IPC 2027 builds on the rules, tools and benchmark domains of the previous HTN IPCs. We thank their organizers – see previous editions – and the authors of the benchmark domains collected for IPC 2020 and IPC 2023.
