The split-point method in this problem is a general method to solve several capacity. Because only the capacity limit is still unable to satisfy each node access only once this limit, the reason is very simple, we draw a diagram to know, assume that there are two paths from the starting point to the same node 2, and then all to the end of N, although they meet the traffic limit but through the same node.So how do we solve this problem? The answer is: the Split method.A node is split into two nod

Everyone else said it was a bare minimum charge stream. After thinking for a long time, I couldn't think of how to do it. I finally understood it after reading other people's problem-solving reports. The key lies in the composition and conversion. The source point is 1. Add a sink point. The edge capacity of the sink point to each city is the opposite of the money that each city sells beer. Use spfa to find the shortest path of the cost. If the cost

Calculate the maximum weight of a bipartite graph (not necessarily the maximum matching),/Charge flow Create a model based on the meaning of the question: to give a mixed graph with some edges, select some edges to maximize the weight and ensure that each vertex's inbound and outbound degrees are at most 1. An error occurred while understanding the question at the beginning. Idea: A Binary Graph with the maximum weight matches, but not all vertices ar

POJ 2195 minimum charge flow Q: to give a messy square matrix, H Represents the home and m represents the people. Now everyone is going home and asking everyone the steps to go home and Idea: I think of the cost flow very well. The cost is the minimum number of steps for people to go home, and the traffic is the number of people. If you connect to the edge, everyone will reach home with a capacity of 1, the cost is the edge of the number of steps. Th
