Beyond Fail-to-Pass: Iterative Hardening of Co-Generated Bug Reproduction Tests and Fixes

Yuhao Tan, Zhibang Yang, Fangkai Yang +9

Large language models (LLMs) have made automated program repair (APR) increasingly practical for real-world bugs, but repairing directly from bug reports remains underconstrained.…

ToolAtlas: Learning Once, Reusing Everywhere with Tool-Side Memory

Yue Fang, Zhibang Yang, Fangkai Yang +5

ToolAtlas introduces a graph‑based, provider‑side memory that records tool capabilities, failure limits, and how tools can be combined, allowing LLM agents to query this memory and…

A Tale of Two Graphs: Separating Knowledge Exploration from Outline Structure for Open-Ended Deep Research

Zhuofan Shi, Ming Ma, Zekun Yao +7

Open-Ended Deep Research (OEDR) pushes LLM agents beyond short-form QA toward long-horizon workflows that iteratively search, connect, and synthesize evidence into structured repor…

Learning to Refine: Self-Refinement of Parallel Reasoning in LLMs

Qibin Wang, Pu Zhao, Shaohan Huang +6

Test-time scaling (TTS) has gained widespread attention for enhancing LLM reasoning. Existing approaches such as Best-of-N and majority voting are limited as their performance depe…
