A '''complex adaptive system''' ('''CAS''') is a [[Systems theory|system]] that is ''[[complex system|complex]]'' in that it is a [[Dynamic network analysis|dynamic network of interactions]], but the behavior of the ensemble may not be predictable according to the behavior of the components. It is ''[[Adaptive system|adaptive]]'' in that the individual and [[collective behavior]] mutate and [[self-organizing|self-organize]] corresponding to the change-initiating micro-event or collection of events.<ref name=CAS-T-01/><ref name=CAS-T-02/><ref name="Miller, John H., and Scott E.
