Community detection in networks by using multiobjective evolutionary algorithm with decomposition

Gong, Maoguo; Ma, Lijia; Zhang, Qingfu; Jiao, Licheng - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 15, pp. 4050-4060

Community structure is an important property of complex networks. Most optimization-based community detection algorithms employ single optimization criteria. In this study, the community detection is solved as a multiobjective optimization problem by using the multiobjective evolutionary...

Synchronization on overlapping community network

Wu, Jianshe; Wang, Xiaohua; Jiao, Licheng - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 3, pp. 508-514

In this paper, we propose a simple random network model with overlapping communities controlled by several parameters, and investigate the influence of the overlapping community structure on the synchronization behavior under different parameters. It is found that the synchronizability of the...

Fractal analysis on human dynamics of library loans

Fan, Chao; Guo, Jin-Li; Zha, Yi-Long - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 24, pp. 6617-6625

In this paper, the fractal characteristic of human behaviors is investigated from the perspective of time series constructed with the amount of library loans. The values of the Hurst exponent and length of non-periodic cycle calculated through rescaled range analysis indicate that the time...

An anti-attack model based on complex network theory in P2P networks

Peng, Hao; Lu, Songnian; Zhao, Dandan; Zhang, Aixin; … - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 8, pp. 2788-2793

Complex network theory is a useful way to study many real systems. In this paper, an anti-attack model based on complex … network theory is introduced. The mechanism of this model is based on a dynamic compensation process and a reverse percolation … fragmentary peers of an attacked P2P network together into a giant connected component. In this way, the model based on complex …

Self-organized network design by link survivals and shortcuts

Hayashi, Yukio; Meguro, Yuki - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 3, pp. 872-879

One of the challenges for future infrastructures is how to design a network with high efficiency and strong connectivity at low cost. We propose self-organized geographical networks beyond the vulnerable scale-free structure found in many real systems. The networks with spatially concentrated...
