WebIn this note, we show how the determinant of the distance matrix D(G) of a weighted, directed graph G can be explicitly expressed in terms of the corresponding determinants for the (strong) blocks G i of G. In particular, when cof D(G), the sum of the cofactors of … WebAll graphs (digraphs) have distance matrices, graphs having symmetric ones and digraphs, in general, asym-metric ones. All entries in the distance matrix of a connected graph are finite. Connected digraphs may have infinite entries. A branch (arc) in a graph (digraph) is redundant if its removal results in a graph (digraph) with the same ...

WebThe matrix of distances. This matrix has size n 2 and associates to any u v the distance from u to v. The vector of eccentricities. This vector of size n encodes for each vertex v the distance to vertex which is furthest from v in the graph. In particular, the diameter of the graph is the maximum of these values.

WebFind the path between given vertices in a directed graph. Given a directed graph and two vertices (say source and destination vertex), determine if the destination vertex is reachable from the source vertex or not. If a path exists from the source vertex to the destination vertex, print it. For example, there exist two paths [0—3—4—6—7 ...
