Web1.4 Directed graphs De nition A directed graph or digraph , D, consists of a set of vertices, V(D), and a set of edges, E(D). Each edge is an ordered pair of vertices. If e = (u,v), we call u the tail and v the head of the edge u. Digraphs are used to model nite automata and Markov chains, and also to represent functions from a nite set to itself. WebFeb 2, 2024 · You could create a graph, and then convert it to a directed graph.
