加权网络的多重分形分析
Multi-fractal analysis of weighted networks
摘要:
在许多实际的复杂网络中,发现了分形和自相似的性质,分形维数是描述复杂网络分形性质的一种有效方法。如果只取一个分形维数来研究复杂网络,分形分析是不够的。在这种情况下,复杂网络的多重分形分析受到关注。而加权网络的多重分形维数研究较少。基于加权网络分形维数的盒覆盖算法(BCANw),提出了加权网络的多重分形维数。将该方法应用于实际网络的分形维数计算。数值结果表明,该方法是分析加权网络分形性质的有效方法。
英文摘要:
In many real complex networks, the fractal and self-similarity properties have been found. The fractal dimension is a useful method to describe fractal property of complex networks. Fractal analysis is inadequate if only taking one fractal dimension to study complex networks. In this case, multifractal analysis of complex networks are concerned. However, multifractal dimension of weighted networks are less involved. In this paper, multifractal dimension of weighted networks is proposed based on box-covering algorithm for fractal dimension of weighted networks (BCANw). The proposed method is applied to calculate the fractal dimensions of some real networks. Our numerical results indicate that the proposed method is efficient for analysis fractal property of weighted networks.
