Title: | On optimal orientations of cartesian products of graphs (I) | Authors: | Koh, K.M. Tay, E.G. |
Issue Date: | 28-Aug-1998 | Citation: | Koh, K.M.,Tay, E.G. (1998-08-28). On optimal orientations of cartesian products of graphs (I). Discrete Mathematics 190 (1-3) : 115-136. ScholarBank@NUS Repository. | Abstract: | For a graph G, let script D sign(G) be the family of strong orientations of G, and define d⇀(G)= min{d(D)] D ∈ script D sign(G)}, where d(D) denotes the diameter of the digraph D. Let G x H denote the cartesian product of the graphs G and H. In this paper, we determine completely the values of d⇀(Km x Pn), d⇀(Km x Kn) and d⇀(Kn x C2k+1), except d⇀(K3 x C2k+1), k≥2, where Kn, Pn and Cn denote the complete graph, path and cycle of order n, respectively. © 1998 Elsevier Science B.V.
