CF723E One-Way Reform
很有意思的一个题,刚开始想复杂了后面看了题解才发现是个傻逼题 首先不难发现答案的上界数就是度数为偶数的节点数,考虑一种构造方法能打到这个上界 不妨新建一个虚拟节点,将所有度数为奇数的点与其连边,这样图中所有点度数都变成了偶数,包括这个虚拟节点 而对于一个所有点度数均为偶数的图,我们知道它一定存在欧拉 ......

P4652 [CEOI2017] One-Way Streets 基础图论。 题目中是关于无向图边方向的问题,而边双有一个优秀的性质:边双内的任意两点间至少有两条不经过同样的边的路径,因此对于边双内的边无论有没有题目中 \(x\) 能走到 \(y\) 的限制,它的方向都是不能确定的,因此首先边双缩点 ......

Paper Reading: A three-way decision ensemble method for imbalanced data oversampling
针对 SMOTE 的缺点,本文提出了一种基于建设性覆盖算法(CCA)的三向决策抽样方法(CTD)。CTD 首先使用 CCA 构造不平衡数据的覆盖,然后选择少数样本的覆盖并根据覆盖的密度划分为三个区域。最后根据覆盖分布规律得到相应的阈值 α 和 β,选择关键样本进行SMOTE过采样。考虑到 CCA 随... ......
【CF1715E】Long Way Home
这个 $k$ 非常小,所以我们考虑全部依次飞这 $k$ 次行程。 这个飞来飞去是一个平方的形式,我们考虑优化这一形式。 首先我们知道从 $u$ 飞到 $v$ 后就可以这样做: $$dis_u + (u -v)^2 \to dis_v$$ $$dis_u + u^2 + v^2 - 2uv \to d ......

看到 `shortest paths` 来做的。 首先有一个贪心的策略,对于当前点 $u$ 若不能直接往后走则肯定是选择经过的点中 $w_i$ 最大的加。 很好理解,证明就不需要了。 所以可以定义状态 $f_{u, mx}$ 为 $u$ 点最大能加的值为 $h_{mx}$ 的最优状态,$h$ 是 $ ......
