Plan Then Action:High-Level Planning Guidance Reinforcement Learning for LLM Reasoning

Zhihao Dou, Qinjian Zhao, Zhongwei Wan +10

Large language models (LLMs) demonstrate strong reasoning abilities via Chain-of-Thought (CoT), but their token-level generation encourages local decisions and lacks global plannin…
