The diameter of a graph In a graph G, the distance between two vertices uand v, denoted by d(u;v), is de ned to be the length of a shortest path joining uand vin G. (It is …
WebNov 27, 2024 · If you want to measure the diameter of a circle, you would measure from one end of the circle to the other. You wouldn't measure from somewhere in the middle of the circle to the outside. Similarly to how diameter is defined for graph theory, the diameter of a circle is also the largest distance between two points in the circle. … WebIn graph theory, the degree diameter problem is the problem of finding the largest possible graph G (in terms of the size of its vertex set V) of diameter k such that the largest degree of any of the vertices in G is at most d.

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. … WebJul 3, 2010 · Diameter, D, of a network having N nodes is defined as the longest path, p, of the shortest paths between any two nodes D ¼ max (minp [pij length ( p)).

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.
