# 验证器-生成器协同进化
验证器必须与生成器同步进化——这是 [[verification-horizon-no-silver-bullet|Verification Horizon 论文]] 的核心主张。
## 类比 GAN
类似于 GAN 中 discriminator-generator 的对抗动态Goodfellow et al., 2020但目标是**协作**而非对抗:验证器提供有效的训练信号引导 policy 改进,而非试图击败生成器。
## 论文中的四种形式
1. **Behavior Monitor 的迭代更新**:每轮 RL 后抽样新 trajectory发现新的 shortcut 行为模式 → 更新 pattern set `P`
2. **Interactive Judge 对静态 Judge 的替代**:当静态 judge 被长度利用破解后,交互式 judge 通过运行时行为评估恢复鲁棒性
3. **用户反馈作为持续信号源**:真实用户交互产生 on-policy 信号,驱动下一轮 policy 改进
4. **Agent Evaluator 的循环升级**评估器提示的迭代v1→v4正是协同进化的微观体现
## 关键洞察
"不存在固定奖励函数能在 policy 能力增长下持续有效"——这意味着验证不是一次性设计问题,而是**持续运维问题**。验证系统必须作为训练管线的核心基础设施不断重建。
