WebJul 17, 2024 · Graphs, Vertices, and Edges. A graph consists of a set of dots, called vertices, and a set of edges connecting pairs of vertices. While we drew our original graph to correspond with the picture we had, there is nothing particularly important about the layout when we analyze a graph. Both of the graphs below are equivalent to the one drawn … WebThe average degree of an undirected graph is used to measure the number of edges compared to the number of nodes. To do this we simply divide the summation of all nodes’ degree by the total number of nodes. For example in the graph above the nodes have the following degrees: A=2, B=2, C=4, D=2, E=3, F=2, G=2, H=1.

WebIf the sum is even, it is not too hard to see that the answer is yes, provided we allow loops and multiple edges.
