The directed edges of a digraph are thus defined by ordered pairs of vertices (as opposed to unordered pairs of vertices in an undirected graph) and represented with arrows in visual representations of digraphs, as shown below. sid meier\u0027s civilization 7

"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.

WebTopological sorting. In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edges may represent ... WebLet G = (V, E) be an undirected graph, where V is the set of vertices and E is the set of (undirected) edges. Let u, v ∈ V be vertices of G. Let e = {u, v} ∈ E be an edge of G.
