What is Complex system?
{{Complex systems}} A '''complex system''' is one where smaller elements make [[complexity|complex]] things happen. These smaller elements can be simple elements or they can be complex systems within themselves. Any such complex elements can be interrelated in simple or complex ways and may be hard to identify as distinct. ==Abstract== 'Complex systems' is a field which studies the common properties of [[system]]s considered [[complex]] in [[nature]], [[society]] and [[science]]. It is also called ''complex systems theory'', ''complexity science'', ''study of complex systems'' and/or ''sciences of complexity''. ==Problems== The key problems of such systems are difficulties with their formal [[modeling]] and [[simulation]]. From such perspective, in different research contexts complex systems are defined on the base of their different attributes. ==Related pages== *[[Self-organization]] {{tech-stub}} {{authority control}} [[Category:Systems]]
