Abstract: As a crucial branch of machine learning,reinforcement learning has been widely applied in various complex decision-making tasks.In recent years,with the rapid development of large language models,the application of reinforcement learning in large language models has gradually become a research hotspot.This paper reviews the fundamental principles of reinforcement learning and systematically organizes common reinforcement learning algorithms,including value-based,policy-based,and model-based reinforcement learning algorithms.Building upon this foundation,it categorizes existing reinforcement learning algorithms in large language models from a novel perspective,discusses challenges faced by reinforcement learning in the field of large language models.Finally,this paper highlights that optimizing reinforcement learning algorithms to enhance computational efficiency and training stability remains a key direction for future research.
