complexity theory

a field that studies nonlinear systems with very large numbers of interacting variables using mathematical modeling and computer simulation. In general, it proposes that such systems are too complex to be accurately predicted but are nevertheless organized and nonrandom. Complexity theory has important applications in such fields as ecology, epidemiology, finance, and information science. See also chaos theory; dynamic systems theory.
