# Risky Bellman Equation
> [[safe-equilibrium-exploration|SEE 算法]] 中用于计算最大 [[feasible-zone|可行域]] 的核心方程——在模型不确定性下,量化状态-动作对的"风险"(最坏情况下的约束违反可能性)。
## 在 SEE 中的作用
SEE 的第 1 步:固定 [[uncertain-model|不确定模型]] M通过求解 Risky Bellman Equation判定哪些状态-动作对在 M 的最坏情况假设下仍能保持安全。
## 与传统 Bellman 方程的区别
| 传统 Bellman | Risky Bellman |
|-------------|---------------|
| 优化期望累积奖励 | 评估最坏情况约束违反 |
| 确定性转移 | 不确定性范围转移 |
| 收敛到最优价值函数 | 收敛到最大可行域 |
