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. WebExplore math with our beautiful, free online graphing calculator.

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 ...
WebA line graph L(G) (also called an adjoint, conjugate, covering, derivative, derived, edge, edge-to-vertex dual, interchange, representative, or theta-obrazom graph) of a simple graph G is obtained by associating a vertex with each edge of the graph and connecting two vertices with an edge iff the corresponding edges of G have a vertex in common … WebOn Moore Graphs with Diameters 2 and 3 Abstract: This note treats the existence of connected, undirected graphs homogeneous of degree cI and of diameter Ie, having a …
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 …
