Design, Utilization, Self-adaptation and Control
The emergent behaviour of complex systems is very desirable, because emergence is characterized by the fact that the whole is more than the sum of the parts.
In Computer Science, for instance, getting n computers to work together on a single problem usually means obtaining a speedup <n, because the n computers must communicate and synchronize to exchange their partial results.
If the n computers implement a complex system, one could hope to not only obtain a speedup of n, but possibly a supralinear speedup, >n. This behaviour is regularly observed when evolutionary algorithms are implemented on n computers.
In catalysis, the control of the nature and strength of the interactions between the catalytically active sites allows the tuning of the properties of the system, for example the reaction selectivity, the emergence of dynamic behaviour, or the formation of self-organized spatial patterns.
This is also true in Chemistry, Biology, Physics, ... so designing complex systems is what this page is about, with the objective to use the designed complex system and benefit from its complex behaviour. Ideally, synthetised complex systems should show self-adaptation ability and one should be able to somehow control them so as to keep them under control and possibly guide them to do what we would like them to do.
