随机网络是研究复杂网络性质的一种常用的零模型。我们描述了一种高效而精确的生成任意两点相关无向随机网络的算法,该算法在顶点之间没有自边或多边。为了系统地研究两点相关性的影响,我们进一步发展了一种构造联合度分布$P(j,k)$的形式,它允许同时确定任意的度分布$P(k)$和任意的平均近邻函数$\kN(k)$。以无标度网络($P(k)\propto k^{-\gamma})和经验复杂网络($P(k)$取自网络)为例,证明了该方法的有效性。最后,我们将我们的算法推广到退火网络,使得网络可以用类似平均场的方式表示。

英文摘要:
  Random networks are intensively used as null models to investigate properties of complex networks. We describe an efficient and accurate algorithm to generate arbitrarily two-point correlated undirected random networks without self- or multiple-edges among vertices. With the goal to systematically investigate the influence of two-point correlations, we furthermore develop a formalism to construct a joint degree distribution $P(j,k)$ which allows to fix an arbitrary degree distribution $P(k)$ and an arbitrary average nearest neighbor function $\knn(k)$ simultaneously. Using the presented algorithm, this formalism is demonstrated with scale-free networks ($P(k) \propto k^{-\gamma}$) and empirical complex networks ($P(k)$ taken from network) as examples. Finally, we generalize our algorithm to annealed networks which allows networks to be represented in a mean-field like manner.
