Complex systems
Complex systems is a scientific field which studies the common properties of systems that are considered fundamentally complex. Such systems may exist in nature, society, science and many other fields. It is also called complex systems theory, complexity science, study of complex systems, sciences of complexity, non-equilibrium physics, and historical physics. The key problems of such systems are difficulties with their formal modeling and simulation. From such perspective, in different research contexts complex systems are defined on the base of their different attributes. Since all complex systems have many interconnected components, the science of networks and network theory are always important aspects of the study of complex systems. At present, the consensus related to one universal definition of complex system does not exist yet.
