A complex system is a system made up of many interacting components, where the behavior of the system as a whole cannot be predicted from the behavior of its individual parts. Complex systems can be found in nature, science, engineering, economics, and many other fields. They usually exhibit nonlinear behavior, have emergent properties, and are often characterized by feedback loops and self-organization. Examples of complex systems include ecosystems, the human brain, the internet, and the global economy.
