# 自进化变异Self-Evolutionary Mutation
## 定义
Self-Evolutionary Mutation 是 ACE-Router 的候选空间扩展策略:通过**LLM 驱动的受控变异**,从已有工具合成行为多样化的新工具变体,丰富训练数据的判别难度。
## 五种变异算子
| 算子 | 示例 |
|------|------|
| **Function Enhancement** | `get_stock_prices``get_stock_prices_with_news` |
| **Parameter Mutation** | 修改参数类型、必选/可选、范围 |
| **Workflow Chaining** | 组合多个操作为流水线工具 |
| **Helper Operation** | 创建辅助/便利包装 |
| **Usage Extension** | 扩展至新的使用场景 |
## 为什么要变异
- 真实工具的**功能相似性**使 embedding 难以区分
- 变异生成的"近义词"工具迫使路由器学会精确辨识
- 在噪声实验中,注入的变异工具对 GPT-4o 和 Gemini 造成了严重干扰(准确率降至 28-32%),而 ACE-Router 保持 56%
