This suggests that the degree of each vertex (person) is 5, giving a sum of: 5+5+5+5+5+5+5+5+5 = 45. But after applying the handshake theorem: 2m = 45 yields an answer of 22.5. Digraphs. A directed graph (or digraph ) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. We use the names 0 through V-1 for the vertices in a V-vertex graph.Another name of this graph is Full Graph. 8. Pseudo Graph. The pseudo graph is defined as a graph that contains a self-loop and multiple edges. 9. Regular Graph. If all the vertices of a simple graph are of equal size, that graph is known as Regular Graph. Therefore, all complete graphs are regular graphs, but vice versa is not feasible. 10 ... A complete digraph is a directed graph in which every pair of distinct vertices is connected by a pair of unique edges (one in each direction).
