A graph, G=(V,E), consists of a non empty finite set V of elements called vertices and a set E of pairs of elements of V called edges. The number of vertices N=|G|=|V| is the order of the graph. If (x
Directed graphs with positive edge weights grown by breadth-first search from a random point in the New York City benchmark graphs as included in the 9th DIMACS Implementation Challenge (2005). This a
