## Summary

Recent advancements in Large Language Models (LLMs) have transformed decision-making processes by breaking down complex problems into more manageable language sequences known as "thoughts". However, existing thought designs are limited in their ability to exhibit all three key attributes: performance, efficiency, and flexibility. To overcome these limitations, a novel thought prompting approach called "Everything of Thoughts" (XoT) is introduced. XoT leverages pretrained reinforcement learning and Monte Carlo Tree Search (MCTS) techniques to incorporate external domain knowledge into thoughts, enhancing the capabilities of LLMs and enabling them to efficiently generalize to unseen problems. The XoT approach utilizes a collaborative thought revision framework that combines MCTS with LLMs. This framework autonomously generates high-quality comprehensive cognitive mappings with minimal interactions from the LLM. By incorporating external domain knowledge through reinforcement learning and MCTS, XoT enhances the performance and efficiency of LLMs in solving complex problems. Additionally, XoT empowers LLMs to engage in unconstrained thinking, allowing for flexible cognitive mappings for problems with multiple solutions. This flexibility enables LLMs to consider various perspectives and generate diverse solutions for a given problem. Overall, the XoT approach defies the limitations of existing thought paradigms by incorporating external domain knowledge and enabling LLMs to exhibit all three key attributes: performance, efficiency, and flexibility. This advancement has significant implications for decision-making processes across various domains.
