摘要: 网络邻域抗毁性的研究起源于间谍网。它的特殊性在于当图中一个点失效时其邻点全部失效,然而实际中最可能的情形是,一个点失效时其邻点依概率p失效基于此,提出广义p-邻域离散数的概念,给出若干特殊图及其线图的广义p-邻域离散数计算公式通过分析概率p与参数的关系,说明该参数在刻画网络邻域抗毁性方面的精细之处。

关键词: 图, 邻域离散数, 失效概率, 广义p-邻域离散数, 抗毁性

Abstract: The study of network neighbor invulnerability originated from spy networks. The particularity is that if a vertex has been destroyed, its adjacent vertices will be useless as a whole. However, the most likely situation is that if a vertex has been destroyed, its adjacent vertices will be failed with some probability p. Based on this idea, the concept of general p-neighbor scattering number is proposed. The p-neighbor scattering number formula of some special graphs and line graphs are given. The accuracy of network neighbor invulnerability measure is illustrated by the analysis of the relationship of p and the general p-neighbor scattering number.

Key words: graph, vertex-neighbor-scattering number, failure probability, general p-neighbor scattering number, invulnerability
