Firstly, there should be at most one edge from a specific vertex to another vertex. This ensures all the vertices are connected and hence the graph contains the maximum number of edges. In short, a directed graph needs to be a complete graph in order to contain the maximum number of edges. In graph theory, there are many variants of a directed ...Precomputed edge chromatic numbers for many named graphs can be obtained using GraphData[graph, "EdgeChromaticNumber"]. The edge chromatic number of a bipartite graph is , so all bipartite graphs are class 1 graphs. Determining the edge chromatic number of a graph is an NP-complete problem (Holyer 1981; Skiena …The idea of this proof is that we can count pairs of vertices in our graph of a certain form. Some of them will be edges, but some of them won't be. When we get a pair that isn't an edge, we will give a bijective map from these "bad" pairs to pairs of vertices that correspond to edges.For the complete graphs \(K_n\text{,}\) we would like to be able to say something about the number of vertices, edges, and (if the graph is planar) faces. ... The coefficient of \(f\) is the key. It is the smallest number of edges which could surround any face. If some number of edges surround a face, then these edges form a cycle.

The Turán graph is also the complete -partite graph on vertices whose partite sets are as nearly equal in cardinality as possible (Gross and Yellen 2006, p. 476). A complete graph obviously doesn't have any articulation point, but we can still remove some of its edges and it may still not have any. 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 …So we have edges n = n ×2n−1 n = n × 2 n − 1. Thus, we have edges n+1 = (n + 1) ×2n = 2(n+1) n n + 1 = ( n + 1) × 2 n = 2 ( n + 1) n edges n n.
