Graph Coloring I https://www.nowcoder.com/acm/contest/203/J 题目描述 修修在黑板上画了一些无向连通图,他发现他可以将这些图的结点用两种颜色染色,满足相邻点不同色. 澜澜不服气,在黑板上画了一个三个点的完全图.修修跟澜澜说,这个图我能找到一个简单奇环. 澜澜又在黑板上画了一个n个点m条边的无向连通图.很可惜这不是一道数数题,修修做不出来了. 澜澜非常得意,作为一位毒瘤出题人,有了好题当然要跟大家分享,于是他把这道题出给你做了. 输入描述:…

http://poj.org/problem?id=1419 题意: 一张图黑白染色,相邻点不能都染黑色,最多能染几个黑色点 最大点独立集 但是图不能同构为二分图,不能用二分图匹配来做 那就爆搜吧 还可以转化为补图的最大团问题 #include<cstdio> #include<cstring> #include<iostream> using namespace std; ][]; ],res[]; int n,ans,cnt; void read(int &…

E. Graph Coloring 链接 n个点m条边的无向图,不保证联通,给每个点标号1,2,3.1号点个数n1,2号点个数n2,3号点个数n3.且每条边的两点,标号之差绝对值为1.如果有合法方案,需输出方案. 考虑每个联通子图,2只可以和1或者3连边,1只能和2连边,3只能和2连边,那么将1,3归为一堆,2归为一堆.每一堆内不存在边,构成一个独立点集,那么很明显是一个二分图,每次DFS可以找到二分图两部点的个数,如果存在奇环那么直接输出NO 对于每个联通子图,一个二分图,假设左部有 x 个点…
