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. WebA graph without multiple edges and without loops is called a Simple Graph. Mostly we will deal with simple graphs only. A Walk is a list of vertices and edges ( v 0 e 1 v 1 e 2. . . . e k v k), such that for 1<=i<=k, the edge e i connects v i-1 and v i. A Trail is a walk with no repeated edge. A Simple Path is
