Agentic LLM Planning via Step-Wise PDDL Simulation: An Empirical Characterisation

Researchers introduced PyPDDLEngine, a tool that enables large language models (LLMs) to interactively plan actions in robotic systems using PDDL simulation. The study found that while LLMs can produce shorter plans than classical methods like Fast Downward's seq-sat-lama-2011, their success rate is lower and more dependent on the nature of environmental feedback, highlighting the importance of external verification for effective planning.
