Strengthening Canonical Pattern Databases with Structural Symmetries

2021 · Proceedings of the International Symposium on Combinatorial Search

Symmetry-based state space pruning techniques have proved to greatly improve heuristic search based classical planners. Similarly, abstraction heuristics in general and pattern databases in particular are key ingredients of such planners. However, only little work …

Improved Generalized Planning with LLMs Through Strategy Refinement and Reflection

2026 · Proceedings of the International Conference on Automated Planning and Scheduling

LLMs have recently been used to generate Python programs representing generalized plans in PDDL planning, i.e., plans that generalize across the tasks of a given PDDL domain. Previous work proposed a framework consisting of three …
