Number of edges in complete graph

The Basics of Graph Theory. 2.1. The Definition of a Graph. A graph is a structure that comprises a set of vertices and a set of edges. So in order to have a graph we need to define the elements of two sets: vertices and edges. The vertices are the elementary units that a graph must have, in order for it to exist.

So it seems it can have lesser number of edges than the complete graph. With N vertices, there are a number of ways in which we can construct graph. So this minimum number should satisfy any of those graphs.The graph G= (V, E) is called a finite graph if the number of vertices and edges in the graph is interminable. 3. Trivial Graph. A graph G= (V, E) is trivial if it contains only a single vertex and no edges. 4. Simple Graph. If each pair of nodes or vertices in a graph G= (V, E) has only one edge, it is a simple graph.3. Any connected graph with n n vertices must have at least n − 1 n − 1 edges to connect the vertices. Therefore, M = 4 M = 4 or M = 5 M = 5 because for M ≥ 6 M ≥ 6 we need at least 5 edges.
