Between two randomly selected persons in the world, roughly how many friends are there connecting them together? How are people infected by epidemics such as AIDS and bird flu all over the world? All of these are typical examples of complex networks. The impact of complex and dynamical networks pervades the physical, biological, and social sciences. Its influence on modern engineering and technology is notable and will be far-reaching. Since the discoveries of Watts and Strogatz on small-world networks, and those of Barabási and Albert on scale-free networks, many studies on various real-world networks have been carried out and reported from different points of view. The recent study of complex networks has attracted interest to the modeling and understanding of complex networks. In the past few decades, we have witnessed great success of the study in the coordination dynamics or cooperative collective behaviors of autonomous agents in complex networks.
This special issue focuses on modeling, analysis, control, and applications of real-world complex systems.
