http://acm.hdu.edu.cn/showproblem.php?pid=6178 题意:现在有一n个顶点的树形图,还有k只猴子,每个顶点只能容纳一只猴子,而且每只猴子至少和另外一只猴子通过边相连,现在要删边,保留最少的边使得满足题意. 思路: 贪心的想一想,顶点两两匹配时一条边的贡献值就是两只猴子,那这不就是二分匹配吗.所以先求个二分匹配即可,然后如果此时还是不够的话,那么剩下的猴子每只猴子都需要一条边. 如果用二分匹配的算法可能不太行,虽然看别人用Hopcroft-Carp算法跑了…

http://acm.hdu.edu.cn/showproblem.php?pid=6178 [题意] 给定一棵有n个结点的树,现在有k个猴子分布在k个结点上,我们可以删去树上的一些边,使得k个猴子每个猴子都至少和其他一个猴子相连 问树上最少保留多少条边 [思路] 每个猴子要至少和一个猴子相连,考虑保留的边最少,那么最优的情况一定是一条边的两个顶点放两个猴子,这些边的顶点都不重合 我们现在要找到给定的树中最多有多少条这样的边,即最大二分匹配 O(n)的DFS,对于每个结点,优先与叶子结点形成一条…
