题目大意 给一个无向图,包含 N 个点和 M 条边,问最少删掉多少条边使得图分为不连通的两个部分,图中有重边 数据范围:2<=N<=500, 0<=M<=N*(N-1)/2 做法分析 典型的无向图全局最小割,使用 Stoer-Wagner 算法 Stoer-Wagner 算法共执行 n-1 次 BFS,每次 BFS 得到一个当前图的最小 S-T 割,并且将最后 BFS 的两个点缩点,n-1 次 BFS 得到 n-1 个最小 S-T 割中的最小者就是整个无向图的全局最小割,为了讲述每…

这道题目还是简单的,但是自己WA了好几次,总结下: 1.对输入的总结,加上上次ZOJ Problem Set - 1334 Basically Speaking ac代码及总结这道题目的总结 题目要求输入的格式: START X Y Z END 这算做一个data set,这样反复,直到遇到ENDINPUT.我们可以先吸纳一个字符串判断其是否为ENDINPUT,若不是进入,获得XYZ后,吸纳END,再进行输出结果 2.注意题目是一个圆周,所以始终用锐角进行计算,即z=360-z; 3.知识点的误…
