Learning Adaptive Parallel Execution for Efficient Code Localization

arXiv:2601.19568v2 Announce Type: replace Abstract: Code localization constitutes a key bottleneck in automated software development pipelines. While concurrent tool execution can enhance discovery speed, current agents demonstrate a 34.9% redundant invocation rate, which negates parallelism benefits. We propose FuseSearch, reformulating parallel code localization as a joint quality-efficiency optimization} task. Through defining tool efficiency -- the ratio of unique information gain to invocation count -- we utilize a two-phase SFT and RL training approach for learning adaptive parallel stra

Why this matters
Why now

The proliferation of more autonomous AI agents necessitates solutions for efficient, parallel task execution to overcome performance bottlenecks and redundant operations.

Why it’s important

This research addresses a critical limitation in AI agents' ability to effectively collaborate and execute complex tasks, directly impacting productivity and the scalability of automated software development.

What changes

The focus shifts from merely parallel execution to optimizing tool efficiency through joint quality-efficiency objectives, leading to more intelligent and less wasteful agentic systems.
