What is the square of a directed graph?
The square of a directed graph G = (V, E) is the graph G2 = (V, E2) such that (u,v) ? E2 if and only if G contains a path with at most two edges between u and v. Describe efficient algorithms for computing G2 from G for both the adjacency-list and adjacency-matrix representations of G.How do you find the square of a graph?
The square of a graph is obtained from by adding new edges between every two vertices having distance two in . A block graph is one in which every block is a clique.- The square of an adjacency matrix A^2=(s_{ij}) has the property that s_{ij} represents the number of walks of length two from vertex i to vertex j. With this information, the motivating question behind this paper was to determine what conditions on a matrix S are needed to have S=A(G)^2 for some graph G.
