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. calvin butts funeral programWebexistence 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.

WebSo 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.

The following lemma shows … WebSince your graph has radius 1 there must be a central vertex v to which all other vertices are connected. Therefore the underlying backbone of your graph family are the star graphs S n (with n + 1 total vertices). Clearly we require n > 1. The graphs in the family must be obtained from adding edges to the star graphs.
