摘要
提出一个非匹配的加权网络模型,其中新节点与旧节点以与度成正比进行择优连接,旧节点之间以与强度成正比进行连接。理论分析与数值模拟结果显示,该网络的度分布、强度分布以及权重分布都具有无标度特征。通过对邻居节点平均度和邻居节点平均强度的研究表明,该网络具有非匹配特性。
We propose a disassortative weighted network model. In the model, at every time step, new node is connected preferentially to some old nodes, and some old nodes are connected to each other preferentially with strength. By the numerical simulations, the distributions of degree, strength and weight of the network show all scale-free nature. Particularly, by the research of the average neighbor degree and the average neighbor strength, one can show that the network has a disassortative property.
