Complex Systems

open access: yes, 2020
Complex systems are systems that display unique properties such as emergence and self-organization. Their behavior is inherently unpredictable due to nonlinear relationships between interdependent parts and processes. This makes complex systems different from systems that are just complicated by possessing many parts.
