一种新增长规则作用下网络的结构性质

提出一种同时考虑加点和去点因素的新型网络增长规则,并系统研究了该规则作用下网络模型的各种宏观结构性质.研究结果表明:去点因素的引入对于网络结构的形成有着很大的影响;新型网络增长规则导致了度分布多样性和度关联的出现,为真实网络中这2种基本性质的起源提供了一种合理解释.该研究结果将有助于揭示复杂网络系统形成和演化的一些内在规律.

Study on structural properties of network under a novel growth rule

A novel network growth rule considering node addition and deletion was proposed,and the macro-structural properties of the network model under the action of the rule were investigated systematically.The results indicate that the effect of node deletion on network structure is significant,and that the novel network growth rule leads to the diversity of degree distribution and the degree correlation,giving a reasonable explanation to the origin of these two fundamental properties of real network.The present study is helpful to reveal natural regularities about the formation and evolution of complex network system.
