Example: Directed and undirected edges.How to calculate the number of edges in a complete graph - Quora. Something went wrong.A complete graph is an undirected graph where each distinct pair of vertices has an unique edge connecting them. This is intuitive in the sense that, you are basically choosing 2 vertices from a collection of n vertices. nC2 = n!/(n-2)!*2! = n(n-1)/2 This is the maximum number of edges an undirected graph can have. A complete graph with 8 vertices would have = 5040 possible Hamiltonian circuits. Half of the circuits are duplicates of other circuits but in reverse order, leaving 2520 unique routes. While this is a lot, it doesn’t seem unreasonably huge. But consider what happens as the number of cities increase: Cities.Question: Prove that if a graph G has 11 vertices, then either G or its complement bar G must be nonplanar. (Hint: Determine the total number N11 of edges in a complete graph on 11 vertices; if the result were false and G and its complement were each planar, how many of the N11 edges could be in each of these two graphs?)After picking the edge, it moves the other endpoint of the edge to the set containing MST. A group of edges that connects two sets of vertices in a graph is called cut in graph theory . So, at every step of Prim’s algorithm, find a cut, pick the minimum weight edge from the cut, and include this vertex in MST Set (the set that contains ...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.

You might have a definition that states, that every pair of vertices are connected by a single unique edge, which would naturally rise a combinatoric reasoning on the number of edges. A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with graph vertices is denoted and has (the triangular numbers) undirected edges, where is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs.The quality of the tree is measured in the same way as in a graph, using the Euclidean distance between pairs of points as the weight for each edge. Thus, for instance, a Euclidean minimum spanning tree is the same as a graph minimum spanning tree in a complete graph with Euclidean edge weights.Prerequisite – Graph Theory Basics. Given an undirected graph, a matching is a set of edges, such that no two edges share the same vertex. In other words, matching of a graph is a subgraph where each node of the subgraph has either zero or one edge incident to it. A vertex is said to be matched if an edge is incident to it, free otherwise."Let G be a graph. Now let G' be the complement graph of G.
