Test instructions: There are n points and m bars have a network of edges, each side has two costs:D: Cost of destroying this side B: rebuilding the cost of a two-way sideLooking for such two point sets, so that the point set S points set T satisfies the cost of destroying all the paths of S to T and > destroys all T to S of the cost of the path and + rebuilds these T to s the cost of the bidirectional path and.Idea 1:And then this is the solution to the feasible flow problem of the Yuanhui wit

, however, library.printbooklist (GetTitle) is used, and the corresponding s in the GetTitle function is Publication,t is a string. Why can it be inconsistent with the original definition of printbooklist, which is the power of covariance and contravariance. Since-S is contravariant, and publication is the parent of book, publication can replace (generalize as) book. Because +t is covariant, and string is a subclass of Anyref, string can instead (generalize to) anyref. As a result, the main prog

. Maximum stream After a feasible stream is obtained, upflow attaches the source and the associated arcs to it. When a flow is solved in the residual network, upflow + flow is still a Feasible flow of the source image, therefore, if you find the maximum stream of the residual network, the maximum flow of the source image is obtained.

, plus the maximum flow that runs out, is a feasible maximum flow in the original image (not to reconnect the edge, but to remove the edge of the t->s, that is, to broaden it again.) ） So for this topic, with the inspiration of the previous question, we know this "matrix, and, limit, maximum" can be transformed into network flow problem, source point line, Edge is restricted and; column connection point, Edge for limited and; rows and columns are connected to limit to the corresponding points; t
