The invulnerability or robustness of complex networks against cascading failures under critical node failures is of great realistic meaning. Inspired by other related works, we propose a renewed cascading failure model which should be more suitable for real networks. In this model, the initial node loads are defined as a nonlinear function of the generalized betweenness with a power exponent α, and...
Detecting communities in complex networks is of considerable importance for understanding both the structure and function of the networks. In this paper, we propose an algorithm for community detection. The fuzzy relational model of the networks is established by using global topology information, and then based on the proposed model, the number of communities is determined by adopting spectral analysis...
