题目简单明了，给 n 个点 m 条边 输入整个有向图，输出最大流。 这里用的还是EK算法，用bfs 进行优化，原本的bfs 是设置图的层来避免反向走，而这里看了一下大牛们的新方法，用了一下父节点，用了这种方法，对...
EK现在用起来已经比较熟练了，比较简单的题目，直接就可以解决，但发现EK，其实效率有些低，是O（V*E^2）的，搞不好，还会超时。同时看别人的博客，发现用EK...原题链接：http://acm.hdu.edu.cn/showproblem.php?pid=3

然后总结下错误原因：1、TLE：while（1）下面第四行，先赋值fa[s]=-2,再memset(fa,0,sizeof(fa));导致后面找到增广路后记录flow直接死循环(实在不知道为什么，求解)。说有1000条边，可是只有十五个点，所以实际的边...

解题思路：这是一道最大流模板题。虽然知道dinic算法更适合一些，但还是用来练练Ford-Fulkerson算法。复杂度为O(F|E|))，不知道怎么算的。。。我觉得该算法相较于dinic算法的优点就是代码量小，写的快。...
