Complexity theory

MM Waldrop in his book, Complexity: the emerging science at the edge of order and chaos (1992) noted:

“…that corporations and industries evolve for better survival in a changing environment. And the marketplace responds to changing tastes and lifestyles, immigration, technological developments, shifts in the price of raw materials, and a host of other factors. Finally, every one of these complex, self-organising, adaptive systems possesses a kind of dynamism that makes them qualitatively different …… Complex systems are more spontaneous, more disorderly, ..[yet].. at the same time, however, their peculiar dynamism is also a far cry from the weirdly unpredictable gyrations known as chaos. These complex systems have somehow acquired the ability to bring order and chaos into a special kind of balance.”

Complexity theory arises between order and chaos.

“Complex systems tend to locate themselves at a place we call the edge of chaos. We imagine the edge as a place where there is enough innovation to keep a living system vibrant and enough stability to keep it from falling into anarchy. Only at the edge of chaos can a complex system flourish.” (Malcolm, 1995)

Research has shown that complexity is very similar to chaos theory (Decker, 2000; Flood, 1988) but that it requires a structured environment to exist. The majority of research (Ambos-spies, 1993) into complexity has followed on from chaos theory, but it is still an emergent theory with many unknowns. As a result, there is no standard definition.

Research on complex systems in biology (Phelan, 1995) has focused on the use of cellular automata. These models control single cells via a set of rules or by the state of their immediate neighbours. The Game of Life, a simple computer program that was popular among programmers in the early 1980’s, is a well-known form of cellular automata. (Wolfram, 1986; Hubler, 1986).

Complexity is well suited to specific physical or chemical applications (Lloyd, 1995; AppliedFutures, 1998) as they are very chaotic but are based solely around a well-structured environment. As an example of the potential application of chaos-based theoretical models, see Biomimicry.
