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. 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 ...

We can use this fact to find the graph diameter by computing log n values of A k. Here's how the algorithm works: let A be the adjacency matrix of the graph with an added self loop for each node. Set M 0 = A. While M k contains at least one zero, compute M k+1 = M k2. popular book series for 2nd gradersWebSo 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. popular book series for 5th gradersWeb1 de jan. de 1996 · For a connected graph G that is not a cycle, a path or a claw, let its k-iterated line graph have the diameter diamk and the radius rk.
