Algorithm Analysis: This problem can use DP to do, but my DP thinking is limited, is not familiar with, just recently brush the topic, introduce the minimum cost maximum flow algorithm solution. Think of the top left as the source point, and the bottom right as the meeting point. Walk from the top down once, and then from the bottom to go up once, in fact, it is equivalent to go down from the top two times, that is, fr

Question: poj2135FarmTour. Analysis: If this question is not carefully read, it may be used as the shortest path. the shortest path is not necessarily the best. it is the shortest path of the two, but not necessarily the shortest path. We can use the billing flow to easily solve the problem. The Edge building capacity is 1, the cost is the edge right, and then the source node s connects to 1, and the fee is

In addition, there is a toll in every city, so you can change the Loose Condition in Floyd .. What about the output path ?? I use the successor of the output starting point instead of the precursor to the end point .. Because we care about the smallest Lexicographic Order of paths and the successor of the starting poi
