Successor-Generator Planning with LLM-generated Heuristics

arXiv:2501.18784v5 Announce Type: replace Abstract: Heuristics are a central component of deterministic planning, particularly in domain-independent settings where general applicability is prioritized over task-specific tuning. This work revisits that paradigm in light of recent advances in large language models (LLMs), which enable the automatic synthesis of heuristics directly from problem definitions -- bypassing the need for handcrafted domain knowledge. We present a method that employs LLMs to generate problem-specific heuristic functions from planning tasks specified through successor ge

Why this matters
Why now

Advances in large language models have reached a point where their generative capabilities can be applied to complex problem-solving domains like planning, bypassing traditional handcrafted approaches.

Why it’s important

This development indicates a significant step towards more autonomous and adaptable AI systems, redefining how planning and decision-making heuristics are generated and applied in various operational contexts.

What changes

The reliance on manually engineered domain knowledge for heuristic generation in planning is reduced, enabling more rapid and automated deployment of AI in complex, novel environments.
