"Problem Analysis"It is easy to think that it is best to put p on the edge of the maximum flow.So two-point network flow, determine when the maximum flow can be reached.Traffic is not necessarily an integer, so a real number is required, and the integer is WA.Code#include 　　Bzoj 3130 [Sdoi2013] Cost Flow--network flow

Website traffic has always been the object of webmaster pursuit, because a website want to make money must be inseparable from the flow of support, no matter what the site, under certain conditions, the more traffic is the more benefits, so that the site to increase the flow of methods in addition to the use of SEO, but also can use other ways to But with the search engine algorithm constantly changing, the

The Ford-fulkerson algorithm is a very well understood algorithm. This is probably the case:① constantly starting from the starting point Dfs find a way to the end. If no one is found, the current value is the maximum flow② If there is still a road to the end, then add it to the shortest section, and then make a residual diagram of the diagram. Go on.The following is the Ford-fulkerson maximum flow algorith

I. Linear programming problems and their representations For example: Two. Maximum network flow problem (1) Network G is a simple forward graph, g= (v,e), v={1,2,...,n}. Specify a vertex s in V, called a source and another vertex T, called a sink. There is a ∈e of each edge (v,w) of the graph G, which should have a value cap (v,w) ≥0, called the capacity of the edge. This is referred to as a network of graph G. (2) Network

This means the clover is covered by water for awhile and takes quite a long. Thus, farmer John has built a set of drainage ditches so this Bessie ' s clover Patch is never covered in water. Instead, the water is drained to a nearby stream. Being
