This adds latency and exposes the model to failures from external APIs. The authors, from Huawei Noah's Ark Lab, propose MeCo (Meta-Cognition-oriented trigger), which decides whether a tool or retrieval call is actually… 2. **[RethinkMCTS: Refining Erroneous Thoughts in Monte Carlo Tree Search for Code Generation](https://md.research.elamur.ai/free/en/papers/li-2025-rethinkmcts-refining-erroneous-thoughts-monte/)** *(2025 · 16 citations)* The paper tackles a weakness of tree-search approaches to LLM code generation. Existing methods such as LATS search directly over code and handle mistakes through reflection, which piles up summaries of past errors in memory but never repairs the flawed reasoning itself. The authors propose RethinkMCTS, which runs… 3. **[LoopTool: Closing the Data–Training Loop for Robust LLM Tool Calls](https://md.research.elamur.ai/free/en/papers/zhang-2026-looptool-closing-data-training-loop/)** *(2026 · 6 citations)* Synthetic data pipelines for training tool-calling LLMs are usually static. Data are generated once, without regard to what the model already handles or still gets wrong, and noisy labels from cheaper open-source generators stay in the set. LoopTool addresses this by turning data creation and training into one… 4. **[ColorBrowserAgent: Complex Long-Horizon Browser Agent with Adaptive Knowledge Evolution](https://md.research.elamur.ai/free/en/papers/wang-2026-colorbrowseragent-complex-long-horizon-browser/)** *(2026 · 1 citation)* The paper addresses two obstacles to deploying web-browsing agents in production. First, general-purpose models lack prior knowledge of the many different site layouts and business rules. Second, agents tend to drift away from the goal as interaction sequences grow longer.
