I agree with a small tweak. Yes, the subgraphs would have their own independent phase spaces (especially if topologies were dissimilar). Though, I would not call the independent subgraphs components as they are no longer part of a larger whole. If the subgraphs are independent and not interacting you cease to have one system. You have multiple independent systems each with their own phase spaces. I'll wrap with my position: - I gave three examples of non-biological complex systems based on Russ's initial question - Russ's additional criteria later in the thread are similar to distinguishing criteria for complex living systems vs complex non-living systems. This is an area of research I'm fascinated with and I encourage this line of discussion - If I need to use Russ's criteria, I can't think of a non-biological example. To me it's like asking for a non-biological example of a living system. - I disagree with Russ's claim that all complex systems must satisfy his criteria to be a complex system. It is too limiting.
