Paper Reading: Interpretable Rule Discovery Through Bilevel Optimization of Split-Rules of Nonlinear Decision Trees
对于可解释的分类器本文限制为用简单的数学术语表示，使用非线性决策树(NLDT)将分类器表示为简单数学规则的集合。树的每个非叶结节点表示一个非线性数学规则，将给定条件节点中的数据集划分为两个不重叠的子集。通过限制每个条件节点上的分裂规则结构和决策树深度，保证了分类器的可解释性。在给定条件节点上的非线性... ......

CF1572B Xor of 3
CF1572B Xor of 3 做多了这种题，感觉好套路。。 首先观察操作性质，有一个有解的必要条件：所有值异或和为 $0$，因为每次操作不会改变 $1$ 的个数的奇偶性。然后再观察一下，发现如果从前缀异或和的角度看待这个操作会变得非常简单，大概就是 $$ s_{k-1}, s_k, s_{k+1 ......
