DescriptionGiven a forward graph, each edge has a capacity of C and an expansion fee of W. The expansion fee here refers to the cost of expanding the capacity by 1.Please:1, in the case of no expansion, the maximum flow of 1 to N;2, the maximum flow of 1 to N to increase the minimum required for the expansion of K cost.InputThe first line contains three integer n,m,k, which represents the number of points, sides, and the amount of traffic required to
EDMONDS-KARP: Multiple calls to BFS from S to T can be attempted to reduce the number of calls. is the use of a less costly and efficient augmented approach. consider: In an augmented process, look for multiple augmented paths. The implementation of dfs Dinic algorithm has the following steps: 1: Initialize capacity network and network Flow 2: constructs the residual
of a network not only has capacity, but also the unit flow costs, then we naturally want to maximize the flow at the same time, so that the total cost lower. Therefore, the minimum cost flow is actually a more general model, so its application is also wider.Surprisingly, the problem can be solved without first finding the maximum flow (and of course there are me
