基于时变差别适应度的网络演化模型
Network Evolution Model Based on Time-varying Difference Fitness
摘要
Abstract
Time-varying performance and differentiation of node fitness are abstracted into time-varying difference fitness,and an improved network evolution model based on the fitness is proposed.In the network,the newly joined nodes tend to connect some nodes that have larger degree or attraction.And in the evolution process,the nodes are connected and disconnected with other nodes at any time.On this basis,a series of mechanisms including preferential attachment,random add edges,random delete edges and the nodes' mutual fans are used to achieve the evolution of the network.The influence of node time-varying performance and differentiation on network evolution is analysed seperatly.Through simulation analysis,the model of the distribution follows a power law distribution and with a small world phenomenon,and has high degree of fitting with the real network.The result verifies the correctness and validity of the model.关键词
