Complex System

The theme of the Complexity International Jounal is the field of complex systems, the generation of complex behaviour from the interaction of multiple parallel processes.

Cosma Shalizi says Complex Systems are those with many strongly interdependent variables. This excludes systems with only a few effective variables, the kind we meet in elementary dynamics. It also excludes systems with many independent variables; we learn how to deal with them in elementary statistical mechanics. Complexity appears where coupling is important, but doesn't freeze out most Degrees Of Freedom.

Most Human Systems are complex.

Complex Systems are unpredictable. Sorry.

  • trying to improve them is a Wicked problem.
  • In a complex system, you can't even learn from your own mistakes. (failure)

Hmm, biological complex systems seem to have lots of Slack, or is that just redundancy? While Human System-s of greater complexity seem to have less slack... or am I wrong?
