Abstract

We generalize the concept of the diameter of a graph G = (N, A) to allow for location of points not on the nodes. It is shown that there exists a finite set of candidate points which determine this generalized diameter. Given the matrix of shortest paths, an o (|A|^2^) algorithm is developed and tested.

For a vertex v and a (k ฯช 1)-element subset P of vertices of a graph, one can define the distance from v to P in various ways, including the minimum, average, and maximum distance from v to P. Associated with each of these distances, one can define the k-eccentricity of the vertex v as the maximum d

## Abstract Given a connected graph ฮ“ of order __n__ and diameter __d__, we establish a tight upper bound for the order of the automorphism group of ฮ“ as a function of __n__ and __d__, and determine the graphs for which the bound is attained. ยฉ 2011 Wiley Periodicals, Inc. J Graph Theory.

We consider the diameter of a random graph G n p for various ranges of p close to the phase transition point for connectivity. For a disconnected graph G, we use the convention that the diameter of G is the maximum diameter of its connected components. We show that almost surely the diameter of rand

A lower bound is given for the harmonic mean of the growth in a finite undirected graph 1 in terms of the eigenvalues of the Laplacian of 1. For a connected graph, this bound is tight if and only if the graph is distance-regular. Bounds on the diameter of a ``sphere-regular'' graph follow. Finally,

## Abstract The clique graph __K__(__G__) of a graph is the intersection graph of maximal cliques of __G.__ The iterated clique graph __K__^__n__^(__G__) is inductively defined as __K__(K^nโˆ’1^(__G__)) and __K__^1^(__G__) = __K__(__G__). Let the diameter diam(__G__) be the greatest distance between

## Abstract We investigate a family of graphs relevant to the problem of finding large regular graphs with specified degree and diameter. Our family contains the largest known graphs for degree/diameter pairs (3, 7), (3, 8), (4, 4), (5, 3), (5, 5), (6, 3), (6, 4), (7, 3), (14, 3), and (16, 2). We a
