| 摘 要： | 在网络演化研究领域,以前工作中对于网络演化机制之间的比较并没有公平、统一的标准。该文基于链路预测理论,采用极大似然估计思想建立了一套用于评价网络演化模型的体系。在基于自治系统的数据实验中,比较了GLP和Tang两个演化模型,结果显示GLP优于Tang,而且得到的最优参数也与其提出者给出的均不相同。实验结果表明基于一定规模为真实网络使用新参数生成的网络更加接近真实网络,并且本文的评价框架可以为模型参数的选取提供建议。

| Abstract: | As the previous evaluation methods of evolving models can not be credible because of its inconformity,in this paper,we propose a new method by applying the theory of link prediction and maximum likelihood estimation.Based on the Internet autonomous system networks,we find that GLP is better than Tang which is not agreed with previous results.Moreover,the optimal parameters of these two evolving models are different from the original ones.The experimental results support our optimal parameters with which the... |
