摘要: 在BBV模型和局域世界模型的基础上,提出了一个具有局域世界演化的BBV模型,该模型考虑了局域世界内部加点,加边,局域世界内外加边以及局域世界内减边四步操作。根据理论分析,导出了该模型的节点权值分布。通过合理地设置参数,该模型能自组织演化成幂律指数在2~3范围内的无标度网络,这与现实中的许多复杂网络相吻合。数值仿真验证了理论分析的正确性。因此,该模型更具有一般性。

Abstract: Based on the BBV scale-free model and the local-world model,the BBV weighted network evolving model based on local-world is presented which takes into account of adding and removing edges in the local-world,the weak links between the local-worlds.According to theory analysis,the strength distribution of nodes is obtained and the exponent of power-law can be adjusted between 2 to 3 with regulating the parameters,which accord with power-law exponent in the realistic networks.The numerical simulations prove the accuracy of theoretics analysis.This network model is a generic model.
