无标度网络BA模型的物理内涵及其改进模型的比较

Physical Connotation of BA Scale-free Network Model and Comparative Research on Mending Models

建立合适的网络模型有助于理解和研究网络结构和网络的动力学行为。本文考察了复杂网络的BA模型以及它的改进模型,分析比较每个模型的物理内涵及度分布,讨论了网络演化中择优机制的差异可能对其度分布特征产生重要的影响。并在各模型的基础上提出了一个新的更符合实际的改进模型,为复杂网络模型的更深一步探索提供了一个新思路。

Designing a suitable model is owing to understanding network＇ s structure and dynamic behavior. In this paper, Researching on the BA model and its mending models, analyzing and comparing physical connotation and degree distribution of every model, Authors discuss the difference of preference which is important to affect network＇ s degree distribution. Based on these models, a generic model which is according with practical network is designed. It gives a more study for complex network model.
