Recent advances in computing and network technologies have contributed much to the successful handling of certain problems in biology, physics, economics, and so forth that until recently were thought too difficult to be analyzed. These complex systems problems tend to share a number of interesting properties from a mathematical viewpoint. A key feature of such systems is that the nonlinear interactions among its components can lead to interesting emergent behavior.

The overall aim of this special issue is to bring together the latest/innovative knowledge and advances in mathematics for handling complex systems, which may depend largely on methods from artificial intelligence, statistics, operational research, and engineering, including nonlinear dynamics, time series analysis, dynamic systems, cellular automata, artificial life, evolutionary computation, game theory, neural networks, multiagents, and heuristic search methods. The solicited papers in this special issue should provide solutions, or early promises, to modeling, analysis, and control problems of real-world complex systems, such as communication systems, process control, environmental systems, intelligent manufacturing systems, transportation systems, and structural systems. Potential topics include, but are not limited to:

• Control systems theory (behavioral systems, networked control systems, delay systems, distributed systems, infinite-dimensional systems, and positive systems)
• Networked control (channel capacity constraints, control over communication networks, distributed filtering and control, information theory and control, and sensor networks)
• Stochastic systems (nonlinear filtering, nonparametric methods, particle filtering, partial identification, stochastic control, stochastic realization, and system identification)
