AEvo解决了智能体演化中证据积累与机制修订脱节的问题，做自动化程序优化或长周期搜索的团队可以直接用这个框架提升效率。
论文提出AEvo，一种元编辑框架，将智能体演化视为交互环境，通过元代理观察累积的演化上下文（候选方案、反馈、轨迹、失败记录），并编辑控制未来演化的程序或代理上下文，而非直接生成下一个候选方案。该方法统一了基于程序和基于代理的演化方式，使累积证据在长周期搜索中可操作。在智能体和推理基准测试中，AEvo优于五种演化基线，相对最强基线提升26%。在三个开放式优化任务中，AEvo在相同迭代预算下达到最先进性能。
Harnessing Agentic Evolution
Agentic evolution has emerged as a powerful paradigm for improving programs, workflows, and scientific solutions by iteratively generating candidates, evaluating them, and using feedback to guide future search. However, existing methods are typically instantiated either as fixed hand-designed procedures that are modular but rigid, or as general-purpose agents that flexibly integrate feedback but can drift in long-horizon evolution. Both forms accumulate rich evidence over time, including candidates, feedback, traces, and failures, yet lack a stable interface for organizing this evidence and revising the mechanism that drives future evolution. We address this limitation by formulating agentic evolution as an interactive environment, where the accumulated evolution context serves as a process-level state. We introduce AEvo, a harnessed meta-editing framework in which a meta-agent observes this state and acts not by directly proposing the next candidate, but by editing the procedure or agent context that controls future evolution. This unified interface enables AEvo to steer both procedure-based and agent-based evolution, making accumulated evidence actionable for long-horizon search. Empirical evaluations on agentic and reasoning benchmarks show that AEvo outperforms five evolution baselines, achieving a 26 relative improvement over the strongest baseline. Across three open-ended optimization tasks, AEvo further outperforms four evolution baselines and achieves state-of-the-art performance under the same iteration budget.
