Complexity science is an interdisciplinary field of study that focuses on the understanding of complex systems. It seeks to explain the patterns and behavior of such systems using a variety of different methods. This includes using concepts from probability theory, statistics, dynamic systems, computer science, and complexity theory. It aims to provide frameworks and techniques to make predictions from observed data and to identify emergent behaviors in a system. Studies into complexity often involve observing the interactions between agents, or elements, within a system and applying interdisciplinary approaches to make sense of the collective behavior that emerges from these agents.
