摘要
曾分别研究节点适应度的择优连接、节点的删除及两端择优连接(double preferential attachment,DPA)3种网络演化机制,在现实网络中它们显著并存,文章构建综合这3种机制的网络演化模型,并对该模型进行数理推导,求出度分布,而且将经典的BA网络一般化.结果显示,建立的综合模型具有无标度特性,3种演化机制对网络的度分布具有不同的影响,且利用仿真方法验证了结果.
The researches on the complex evolving network models have been researched separately based on the mechanisms of node otherness,uniform node deletion or double preferential attachment（DPA）.Nevertheless,these three mechanisms of evolving network exist simultaneously in the real network.This paper established an evolving network model by integrating the three mechanisms.The article performed analytic deductions,calculated the degree distribution,and generalized the scale-free model.Finally,the results show that the comprehensive model has the scale-free feature,and the three evolving mechanisms have different influences on the degree distribution of networks,which were also validated by simulations.
