解题关键:使用的挑战程序设计竞赛上的模板,第一道网络流题目,效率比较低,且用不习惯的vector来建图. 看到网上其他人说此题有重边,需要注意下,此问题只在邻接矩阵建图时会出问题,邻接表不会存在的,也体现了邻接表的优越性? edge结构体的第三个变量为from的下标. 模板一: #include<bits/stdc++.h> #define MAX_V 17 #define inf 0x3f3f3f3f using namespace std; typedef long long ll; in…

Flow Problem 题意:N个顶点M条边,(2 <= N <= 15, 0 <= M <= 1000)问从1到N的最大流量为多少? 分析:直接使用Edmonds_Karp算法即可:下面是对增广路的一些理解和代码的解释: 残量:容量-流量: 增广:求出从源点到汇点的一条道路中所有残量的最小值d,把对应的所有边上的流量增加d,反向边(t->s)流量减少d(反向边的cap其实一直是0,只是flow为负了); 技巧:这次的ins的标号是从0开始的,即tot++,之前我都是++t…
