摘要

假设图G的边可靠

而顶点可靠的独立概率为p

以(n

m)表示具有n个顶点m条边的图的集合.若对于所有1 p∈(0

图G均为(n

m)中的最可靠图

则称G为一致最优图.本文证明了完全k部图K(b

(b+1)k h 1

(b+2)h)在其图类中是一致最优的

而当i≥3时

完全k部图K(b

(b+1)k h 2

(b+2)h

b+i)在其图类中不是一致最优的.

Abstract

For a graph G

suppose that edges never fail and vertices operate independently of each other with a constant probability p.Denote by(n

m) the set of graphs with n vertices and m edges.The graph G is called uniformly optimal in(n

m) if

for all vertex-failure probabilities 1 p ∈(0

the graph G is the most reliable graph.This paper proves that the complete k-partite graphs K(b

(b+1) k h 1

(b+2) h) are uniformly optimal in their classes

while for i ≥ 3

the complete k-partite graphs K(b

(b + 1) k h 2

(b + 2) h

b + i) are not uniformly optimal in their classes.
