Analysis:
The limit of the point traffic is converted to the limit of the edge traffic, and the maximum flow is calculated.
Code:
POJ 3498//sep9 #include
The Dinic algorithm, the complexity of On*n*m (n is the number of points, M is the edge count), because the average number of points is less than the amount of edges, so more than Ek (om*m*n) a bit better.

This article to undertake the last article, mainly explained the maximum flow problem Ford-fulkerson solution. But this is a method, not an algorithm, because it contains several implementations with different running times. The method relies on three important ideas: residual networks, augmented paths and cuts. This is covered in detail in this article, and we provide a Java implementation of the method in the next article.
Before introducing three

Then the residual network is augmented, do not forget the positive augmentation, the equivalent of negative reduction, but also to save records in the diagram.Finally, a cut set to get the maximum

This year's problem boils down to: Combinatorial optimization + minimum cost maximum flow two sub problems, a given server location to find the minimum cost maximum flow as the bottom of the algorithm support will be good to improve the final re
Let's start by outlining what IO isYou imagine and think about it. When you edit a text file, forget ctrl+s and close it is not very painful, when you insert a USB stick on your computer to copy a video from a USB stick into your computer hard drive. Are these data on those devices?We can think of this kind of data transmission as a kind of data flow, according to the direction of the flow, memory as the ba

edge from the starting point in the future, you only need to start from the record location (you can actually use the linked list). The advantage is that time accelerates space savings, and the disadvantage is that programming complexity will become larger, so it is recommended to use the adjacency matrix in the case where the topic permits. Gap OptimisationIf a distance fault occurs at the time of the re-marking, it can be proved that the St has no feasible
In large data high concurrent access, there is often a service or interface in the face of the explosion of the request is not available, or even triggered a chain reaction caused the entire system crashes. At this point you need to use one of the technical means to limit the flow, when the request reached a certain number of concurrent or rate, it is waiting, queuing, demotion, denial of service and so on. In the current limit, the two common algorit
