reduced to AD and BC, must be intersect?It turns out that this proposition is not necessarily, but it can be found that when it can be reduced to AD and BC, AD and BC must be disjoint. Doing so will result in AD+BC > AC+BD.So as long as can reduce the side of the right and, must be able to ensure that disjoint. Then the final state becomes the edge right and the smallest state, which is the minimum match. Can be done using the KM algorithm.Appears to be a data problem and cannot be processed us

HDU_2426 This topic is a perfect match for the maximum right. we need to pay attention to two points: 1. Deal with the negative edge. 2. Note that N and M are not necessarily equal. For the processing of the first point, I have seen two ways to deal with: ① all the sides are initialized to the negative side, so that as the N-M between all the edge is to exist to match, if the number of matches with the positive edge weight is N, there is a solution. Otherwise, no solution is available. ② The e

the top is modified to enumerate the edges to find D value, the complexity of O (N2). In fact, the complexity of the KM algorithm can be achieved O (N3). We give each y vertex a "slack" function slack, which is initialized to infinity each time we start looking for an augmented path. While looking for an augmented path, when checking for edges (i,j), if it is not in the equal sub-graph, let

Floyd-w is the shortest distance from any point to any point, because of the high complexity, so in order to only a point to any point of time to easily time out, the Dijkstra algorithm is to solve a point to any point of the distance problem, can be used for the direction of the graph or the graph, only need to pay attention to the initialization of the good, In the same way that the FLOYD-W algorithm uses the critical matrix to store the graph, we also need an array to store the origin (1) dis

HDU_3435 This is a perfect match for minimum weights. When I use the KM algorithm to create an adjacent table, I need to initialize the edge weight to MAX-w [e]. then, find the perfect match of the maximum right and convert the result back. Because it is an undirected graph, we need to create two directed edges for each undirected edge. #include#include#define MAXD 1010#define MAXM 20010#define MAX 10001#define INF 1000000000int first[MAXD], next[MAXM], v[MAXM], w[MAXM], N, M;int yM[MAXD], wM[
