转载:网络流基础篇--Edmond-Karp算法             BY纳米黑客 网络流的相关定义: 源点:有n个点,有m条有向边,有一个点很特殊,只出不进,叫做源点. 汇点:另一个点也很特殊,只进不出,叫做汇点. 容量和流量:每条有向边上有两个量,容量和流量,从i到j的容量通常用c[i,j]表示,流量则通常是f[i,j]. 通常可以把这些边想象成道路,流量就是这条道路的车流量,容量就是道路可承受的最大的车流量.很显然的,流量<=容量.而对于每个不是源点和汇点的点来说,可以类比的想象成没有…

网络流的相关定义: 源点:有n个点,有m条有向边,有一个点很特殊,只出不进,叫做源点. 汇点:另一个点也很特殊,只进不出,叫做汇点. 容量和流量:每条有向边上有两个量,容量和流量,从i到j的容量通常用c[i,j]表示,流量则通常是f[i,j]. 通常可以把这些边想象成道路,流量就是这条道路的车流量,容量就是道路可承受的最大的车流量.很显然的,流量<=容量.而对于每个不是源点和汇点的点来说,可以类比的想象成没有存储功能的货物的中转站,所有“进入”他们的流量和等于所有从他本身“出去”的流量. 最大流…

\(2333\)这是好久之前学的了,不过一直在咕咕咕咕. 一般来讲,正常的网络流笔记一开始都是要给网络流图下定义的.那么我们不妨也来先进行一波这种操作. 那么网络流图,类似于有向图,边上带权,但是这个权值变成了"容量".那么,我们定义容量为\(c(u,v) \in E ? c(u,v) : 0\).在整张图中有一个源点和一个汇点,且对于每个点来说有\[\sum F_{in} = \sum F_{out}\]并且我们人为的将\(S\)的\(F_{in}\)设置为\(0\),\(F_{ou…
