二分图是一个无向图,它的n 个顶点可二分为集合A和集合B,且同一集合中的任意两个顶点在图中无边相连(即任何一条边都是一个顶点在集合A中,另一个在集合B中)。当且仅当B中的每个顶点至少与A中一个顶点相连时,A的一个子集A 覆盖集合B(或简单地说,A 是一个覆盖)。覆盖A 的大小即为A 中的顶点数目。当且仅当A 是覆盖B的子集中最小的时,A 为最小覆盖。-two hours map is an undirected graph, it n vertices can be divided into t

给定一个赋权无向图G=(V,E),每个定点v∈U都有一个权值w(v)。如果U V,且对任意(u,v)∈E有u∈U或v∈U,就称U为图G的一个定点覆盖。G的最小权顶点覆盖是指G中所含顶点权之和最小的顶点覆盖。-Empowering given a undirected graph G = (V, E), each point v ∈ U has a weight w (v). If the UV, and for any (u, v) ∈ E there is u ∈ U or v ∈ U, on

This project discusses different techniques and algorithms used to solve the parameterized Vertex Cover problem. A vertex cover of a graph G(V,E) is a subset of vertices V such that for every edge (u, v) ⊆ E, at least one of the vertices u or v

在二分图中求最少的点,让每条边都至少和其中的一个点关联,这就是二分图的“最小顶点覆盖”。二分图的最小顶点覆盖数 =二分图的最大匹配数。-In seeking bipartite graph fewest points, so that each edge and at least one associated point, which is the bipartite graph of the minimum vertex cover. Bipartite graph of the mini
