WebGraph Terminology. Adjacency: A vertex is said to be adjacent to another vertex if there is an edge connecting them.Vertices 2 and 3 are not adjacent because there is no edge between them. Path: A sequence of edges that allows you to go from vertex A to vertex B is called a path. 0-1, 1-2 and 0-2 are paths from vertex 0 to vertex 2.; Directed Graph: A … css textbox 位置

WebMar 22, 2024 · A vertex cover of an undirected graph is a subset of its vertices such that for every edge (u, v) of the graph, either ‘u’ or ‘v’ is in the vertex cover. Although the name is Vertex Cover, the set covers all edges of the given graph. Given an undirected graph, the vertex cover problem is to find minimum size vertex cover.
