LLM-A*: Large Language Model Enhanced Incremental Heuristic Search on Path Planning

Understand

Path planning is a fundamental scientific problem in robotics and autonomous navigation, requiring the derivation of efficient routes from starting to destination points while avoiding obstacles.

• Traditional algorithms like A* and its variants are capable of ensuring path validity but suffer from significant computational and memory inefficiencies as the state space grows.
• Conversely, large language models (LLMs) excel in broader environmental analysis through contextual understanding, providing global insights into environments.
• However, they fall short in detailed spatial and temporal reasoning, often leading to invalid or inefficient routes.
