Special Issue Information

Dear Colleagues,

In the contemporary studies of complex systems, the network theory frequently plays a fundamental role. This is the natural consequence of the internal system's structures (food chains, epidemic spread, social interactions, efficiency of transport systems, economy networks, clique analysis, power greed blackout, electricity production forecast, and many others). Moreover, the development of network theory made it a universal language suitable for fundamental and applied sciences, e.g., mathematics, physics, biology, social sciences, ecology, transport, economy, or power grid. In this framework, various phenomena can be discussed along network topology, statistical properties, and its evolution, as well as the forecasting of systems.

The Special Issue aims to present original works as well as review papers related to advances in fundamentals and applied studies of structure, evolution, and forecasting of complex networks. 

Potential topics include but are not limited to:

  • Complex networks;
  • Machine learning;
  • Evolving network analysis;
  • Spatiotemporal coherence and clustering;
  • Time series forecasting;
  • Nonlinear time series analysis. 

I cordially invite the authors to submit their recent results to this Special Issue to capture state-of-the-art research in the various aspects of complex network theory.

Community structure is a very interesting attribute and feature in complex networks, which has attracted scholars’ attention and research on community detection. Many single-objective optimization algorithms have been migrated and modified to serve community detection problems. Due to the limitation of resolution, the final algorithm implementation effect is not ideal. In this paper, a multi-objective community detection method based on a pigeon-inspired optimization algorithm, MOPIO-Net, is proposed. Firstly, the PIO algorithm is discretized in terms of the solution space representation, position, and velocity-updating strategies to adapt to discrete community detection scenarios. Secondly, by minimizing the two objective functions of community score and community fitness at the same time, the community structure with a tight interior and sparse exterior is obtained. Finally, for the misclassification caused by boundary nodes, a mutation strategy is added to improve the accuracy of the final community recognition. Experiments on synthetic and real networks verify that the proposed algorithm is more accurate in community recognition compared to 11 benchmark algorithms, confirming the effectiveness of the proposed method.
