PlanU: Large Language Model Reasoning through Planning under Uncertainty

C. Liang, Zeming Gao, Chao Ma, C. X. Lin et autres

Large Language Models (LLMs) are increasingly being explored across a range of reasoning tasks. However, LLMs sometimes struggle with reasoning tasks under uncertainty that are relatively easy for humans, such as planning actions in stochastic environments. The adoption of LLMs for reasoning …
