Description
This talk is about DECIMA's take on Hierarchical Task Network (HTN) planning, the AI planner technology which drives the NPC's high-level decisions. We explain how our implementation performs backtracking (similar to Prolog) over preconditions and present a flow visualization which can help understand the backtracking flow. This talk also touches on how we debug our HTN decompositions in-game. This talk was originally given at Leiden University, as part of the 8th International Summer School on Artificial Intelligence and Games. A longer version titled "HTN planning in DECIMA", was given at Goldsmiths, University of London, as part of the AI and Games Conference 2024.Time
