====Complex adaptive systems====
{{Main|Complex adaptive system}}
Complex adaptive systems (CAS), coined by [[John Henry Holland|John H. Holland]], [[Murray Gell-Mann]], and others at the interdisciplinary [[Santa Fe Institute]], are special cases of [[complex system]]s: they are ''complex'' in that they are diverse and composed of multiple, interconnected elements; they are ''adaptive'' in that they have the capacity to change and learn from experience.

In contrast to [[control system]]s, in which [[negative feedback]] dampens and reverses disequilibria, CAS are often subject to [[positive feedback]], which magnifies and perpetuates changes, converting local irregularities into global features.
