WebMar 24, 2024 · A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with n graph vertices is denoted K_n and has (n; 2)=n(n-1)/2 (the triangular numbers) undirected edges, where (n; k) is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs. … WebAug 8, 2024 · 1.

Webthe exact diameter of such large graphs as social networks, the Web, etc. We begin to address these problems by de-veloping a vertex programming algorithm for measuring the exact diameter of a graph. In graph theory, the eccentricity (v) of a vertex vis the greatest geodesic distance between vand any other vertex in the graph. It may also be ... A metric space defined over a set of points in terms of distances in a graph defined over the set is called a graph metric. The vertex set (of an undirected graph) and the distance function form a metric space, if and only if the graph is connected. The eccentricity ϵ(v) of a vertex v is the greatest distance between v and any other vertex; in symbols,

I tried to show this using induction, since it's true for the base cases n = 2 and n = 3 . Now, if I assume that it is true for some m ∈ N - let's first assume that m is odd. Then the largest distance is m − 1 2.
