题目链接 Problem Description Network flow is a well-known difficult problem for ACMers. Given a graph, your task is to find out the maximum flow for the weighted directed graph. Input The first line of input contains an integer T, denoting the number of…
最大流最小割 Introduction Mincut Problem 最小割问题,输入是带权有向图,有一个源点 s(source)和一个汇点 t(target),边的权重在这里称作容量(capacity),是个正数. st-cut(cut): 把图的点分成两个集合 A 和 B,源点 s 和汇点 t 分别属于集合 A 和 B. capacity: 从集合 A 的点指向集合 B 的点的边的权重之和,如下图. 最小割问题就是找到使 capacity 最小的划分(st-cut),即阻隔从源点到汇点的最小…
