摘要
当人们考虑边不出故障,而点的故障概率为独立且相等的P的网络时,点故障网络可靠性R(G,P)定义为图G保持连通的概率。记Ω(n,3)为所有n点e边图的集合,那么图G∈Ω(n,3)称为一致最可靠图(UOR图),如果对于VP∈(0,1)VH∈Ω(n,3)都有R(G,P)≥R(H,P)。本文证明了n≤e〈2(n-2)时不存在UOR图。
The relabilty R (G, p) of a gragh G is the probability that G is eennected given that the edges of G are perfectly reliable and the nodes of survive independently with equal probaility p, Let Q (n, e )be the set of graphs with n nodes and e edges, a graph G∈Ω (n, e) to be uniformly optimal reliable graph if R (G, p)≥ R(H, p), for all H∈Ω(n, e) and all pC (o, 1), In this paper, we show that for n≤e〈2 (n-2)no uniformly optimal reliable graph .exist.
