+# FETCH: Efficient Tree Search for LLM Reasoning
+
+This repository contains model checkpoints for the FETCH framework, as described in the paper [Don't Get Lost in the Trees: Streamlining LLM Reasoning by Overcoming Tree Search Exploration Pitfalls](https://arxiv.org/abs/2502.11183).
+
+The FETCH framework improves the efficiency and accuracy of LLM-based reasoning by addressing over-exploration and under-exploration issues in tree search algorithms.
+
+
+Pre-trained models mentioned in the paper's README are available on Hugging Face Hub:
