# Clique Decision Problem
|
||||
|
||||
> [[safe-equilibrium-exploration|SEE 算法]] 第 2 步将寻找最小 [[uncertain-model|不确定模型]] 的问题**归约为图论中的团判定问题**(给定图 G 和整数 k,判定 G 是否包含大小为 k 的团),并在多项式时间内近似求解。
|
||||
|
||||
## 归约逻辑
|
||||
|
||||
SEE 将模型精化建模为:在不确定性图中找一个"团"——相互兼容的模型参数集合,使得团内所有参数对可行域内数据的拟合都是"最小不确定的"。
|
||||
|
||||
## 计算性质
|
||||
|
||||
- Clique Decision 是 NP-完全的经典问题
|
||||
- SEE 采用多项式时间近似求解
|
||||
- 在实验规模的图上是高效的
