BZOJ 2561: minimum spanning tree [minimum cut/maximum stream]

Tags: des http io ar OS sp for data onDescriptionGiven a connected undirected graph G = (V, E) with the positive weight of a side, where N = | V |, M = | E |, N points are numbered from 1 to N, given three positive integers u, v, and L (u ne; v), we suppose that we add an edge (u, v) with the edge weight of L ), so how many edges need to be deleted to make this edge appear on the minimum generation tree or the maximum generation tree?InputThe first line contains two integers separated by spaces

The first question directly runs the maximum flow can. The plan is built according to the cost flow, the cost is 0.For the second question, in the first question Dinic the remainder of the network to build, the original image of each side (I,J), built (I,J,INF,CIJ), that the cost of C can be augmented by the road. Then from the new source point, the s,1,k,0 represents the traffic to increase the K. Run the minimum cost maximum flow.#include #include #include #include using namespaceStdConst intn

theoretical boundary [9] to ensure stable recovery.Let $i = lj$ is the total number of iterations and uses the Lagrange mean theorem, which has$\delta x_n^{(i)}-\delta x_n^{(i)} = \frac{{\partial g}}{{\partial \bar x}}\left ({\xi _n^{(i)}} \right) \left ({x_n^{(i -1)}-x_n^{(I-1)}} \right) $, (1)where $\xi _n^{(i)}$ falls between $x_n^{(I-1)}$ and $x_n^{(I-1)}$. When the iteration terminates, there are $\delta x_n^{(I)} \to 0$ and $\delta x_n^{(I-1)} \to {x_n}$, where ${x_n}$ is the nth element
