Let G be a directed graph such that every edge e of G is associated with a positive integer, called the index of e. Then G is called a network graph if, at every vertex v of G, the sum of the indices ...

This is a preview. Log in through your library . Abstract Directed acyclic graphs are widely used to describe directional pairwise relations. Such relations are estimated by reconstructing a directed ...

Well, if I remember my graph theory well enough, if A is the adjacency matrix of the graph, each entry of A^n is the number of ways to get between the corresponding nodes in n steps or less. So, to do ...
