| 摘 要： | 在不改变网络度分布的前提下，采用随机交叉机制对网络的同步能力进行优化，提出了一种无标度网络的同步优化网络模型．在同步能力提高的过程中，观察网络匹配特性、聚类系数、特征路径长度和最大介数的变化趋势．仿真结果表明，对于类型Ⅰ无标度网络，最大介数与同步能力没有相关性，而对于类型Ⅱ无标度网络，最大介数随着同步能力的增加而减小．无论哪一种类型的无标度网络，网络同步能力增加时同配特性均降低．

| Abstract: | Based on random interchanging mechanism and restricting the degree distribution of network, the synchronization-optimal scale-free network model was proposed. During the course of enhancing synchronizability of network, the changing of assortative coefficient, clustering coefficients, characteristic path length and maximal betweenness were investigated. Simulations showed, there was no relativity between maximal betweenness and synchronizability of Type I network. However, maximal betweenness decreased as the increase of synchronizability of Type II network. Simulations indicated that the disassortative increased as the increase of synchronizability for both Types network. |
