On the line graph of a graph with diameter 2
Webexistence of a Moore graph with (n;d;D) = (3250;57;2) is a challenging open problem in graph theory. If D 3, Moore graphs exist only for (n;d) = (2D +1;2), which are cycles of odd length. The inequality (1.1) immediately implies a lower bound on the diameter of any d-regular graph of order n. For any n and d, every connected d-regular graph of ... Web24 de mar. de 2024 · Graph Diameter. The graph diameter of a graph is the length of the "longest shortest path" (i.e., the longest graph geodesic) between any two graph vertices , where is a graph distance . In other words, a graph's diameter is the largest number of vertices which must be traversed in order to travel from one vertex to another when …

Web30 de mai. de 2024 · A quasi-strongly regular graph with parameters (n, k, \lambda ; \mu _1, \mu _2, \ldots , \mu _s) is proper if its grade equals s. Note that in such a case the graph is connected with diameter 2 if and only if \mu _i \ge 1 for all 1 \le i \le s. Note that each edge-regular graph is quasi-strongly regular of some grade. Web24 de mar. de 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. …
Web3 de jul. de 2010 · To find the diameter of a graph, first find the shortest path between each pair of vertices. The greatest length of any of these paths is the diameter of the graph. … WebExamples of using a straight line graph to find a formula. Example 1: To show that πR 2 gives the area of a circle. For any circle π is the number 3.14 in the equation: circumference = 2π x radius or π x diameter. So π is circumference diameter. Starting from that (as a definition of π) we can show that the area of a circle is πR 2.

WebHence, for any such graph, the diameter is infinite. If q = (), there is exactly one p, q graph, namely the com-plete graph Kp, and its diameter is 1. We now restrict ourselves to connected p, q graphs for which p -1 < q < (2 and show that the minimum diameter among all such graphs is 2 by exhibiting one with diameter 2.
Web4 de jul. de 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)). In this equation, pij is the length of the path between nodes i and j and length (p) is a procedure that returns the length of the path, p. For example, the diameter of a 4 4 Mesh D ¼ 6. how much kg is 1 stoneWeb31 de mai. de 2015 · The diameter of a graph obtained by identifying two vertices into one new vertex is at most the diameter of the original graph. The following lemma shows … how do i know if my diabetes is getting worseWebSo again, the diameter and the radius are both 1. For the complete bipartite graph K m, n, you need two steps to reach any vertex so the radius and the diameter are both 2. The exception to this is when m or n is 1. In that case, the single vertex can reach any other vertex in a single step so the radius is reduced to 1. how much kg in a tonWebApr 5, 2013 at 8:36. 1. It is actually not bounded by n/k. Take for example the following 3-regular graph: start with one vertex adjacent to all the vertices of a path on 3 vertices.
