Complex networks is a field of study that focuses on the analysis and modeling of complex systems composed of interconnected elements. These interconnected elements can range from biological organisms, social networks, transportation systems, and information networks, among others. The study of complex networks typically involves the application of network theory, graph theory, and statistical analysis to understand the structure, behavior, and dynamics of these interconnected systems. Researchers in this field often seek to uncover patterns, correlations, and properties of complex networks to gain insights into the underlying mechanisms that drive their emergence and evolution. This research area has applications in various fields, such as biology, sociology, computer science, and physics.
