摘要
构造了一种择优选择小世界网络模型,在该模型的基础上研究了复杂网络中各种因子(如特征路径长度、度分布、簇系数和介数等)对同步性能的影响。发现在特征路径长度和簇系数都相同的情况下,网络的同步能力仍然可以存在较大的差异。仿真结果表明,特征路径长度和簇系数都不能单独表征网络的同步能力,节点度分布的不均匀性本质上抑制了网络的同步能力,网络中节点的最大介数是表征网络同步能力的一种合理的物理量。
A small-world network model with preferential attachment is constructed,based on which the effects of various factors such as the characteristic path length,degree distribution,clustering coefficient and betweenness on the synchronizability of complex networks are investigated.It is found that networks with equal characteristic path length and clustering coefficient can still have very different synchronizability.Simulation results show that neither the characteristic path length nor the clustering coefficient of complex networks can solely determines the synchronizability of complex networks,the heterogeneity of the degree distribution essentially suppresses the synchronizability of complex networks,and the maximal betweenness is a reasonable indicator for synchronizability.
