There is only the constant interaction, interplay and co-evolution that demand that we pay constant attention to balance and to feedback. Optimised systems, as I understand them, are also not a view consistent with complex adaptive systems and emergence. To interpret John Holland's work into this context, the appropriate approach is the constant seeking of improvement and potentially useful variation rather than optimisation. The term optimisation assumes a knowledge of what is possible but complexity and emergence are powerful approaches because they recognise that possibility is too large a space to cover or know. What is called for in this thinking is strategies of exploration rather than optimisation.
