WebSep 29, 2024 · A graph with a number (usually positive) assigned to each edge is called a weighted graph. (A graph without weights can be thought of as a weighted graph with all weights equal to 1.) We denote the weight between vertices \(u\) and \(v\) by \(w(u,v)\). Webmatrix B(G)ofG is the m⇥n matrix whose entries bij are given by bij= (+1 if ej = {vi,vk} for some k 0otherwise. Unlike the case of directed graphs, the entries in the incidence matrix of a graph (undirected) are nonnegative. We usually write B instead of B(G). The notion of adjacency matrix is basically the same for directed or undirected graphs. hemibagrus macropterus https://studiolegaletartini.com
