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

Drainage ditches Time Limit: 1000MS Memory Limit: 10000K Total submissions: 58538 accepted: 22485 Description Every time it rains on farmer John's fields, a pond forms over Bessie ' s favorite clover. 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

The input stream, the output stream is exactly how to distinguish, in writing code often encounter problems, or often confusing to find two of the relationship between streams. Through today's study to make a note, but also to provide everyone to learn, at the same time ask me questions. The book saysInput stream: Data can only be read from and cannot be written to.Output stream: Data can only be written to it and cannot be read from. So I have a question, what the hell is this stream? The b

A long time ago, I tried to overcome the problem of network streams. I think this part of content seems very advanced, and I think there are still many other algorithms to learn, third, I think it would be better to supplement the relevant algorithms first. However, although this is a relatively advanced graph theory, it is still not difficult to build a foundation, and there are not many related algorithms. You can learn it after you are familiar with graph theory, the algorithm can be learned
