Adhoc constructions sometimes also provide good ...The main characteristics of a complete graph are: Connectedness: A complete graph is a connected graph, which means that there exists a path between any two vertices in the graph. Count of edges: Every vertex in a complete graph has a degree (n-1), where n is the number of vertices in the graph. So total edges are n* (n-1)/2.
