of such a non-transparent model. A white-box model of complex dynamic system has 'transparent walls' and directly shows underlying mechanisms. All events at micro-, meso- and macro-levels of a dynamic system are directly visible at all stages of its white-box model evolution. In most cases mathematical modelers use the heavy black-box mathematical methods, which cannot produce mechanistic models of complex dynamic systems. Grey-box models are intermediate and combine black-box and white-box approaches. Creation of a white-box model of complex system is associated with the problem of the necessity of an a priori basic knowledge of the modeling subject. The deterministic logical ] are necessary but not sufficient condition of a white-box model. The second necessary prerequisite of a white-box model is the presence of the physical ] of the object under study. The white-box modeling represents an automatic hyper-logical inference from the ]s because it is completely based on the deterministic logic and axiomatic theory of the subject. The purpose of the white-box modeling is to derive from the basic axioms a more detailed, more concrete mechanistic knowledge about the dynamics of the object under study. The necessity to formulate an intrinsic ] of the subject before creating its white-box model distinguishes the cellular automata models of white-box type from cellular automata models based on arbitrary logical rules. If cellular automata rules have not been formulated from the first principles of the subject, then such a model may have a weak relevance to the real problem.<ref name="Kalmykov Lev V., Kalmykov Vyacheslav L.

article on "massive things". Would you argue that it should be split into three articles? 1) things that are massive. 2) the field that studies them (physics) and 3) a paradigm (e.g. newton's, or aristotle's)? That would seem odd. Why? Well, the theories of Newton and Einstein kind of *define* massive things. I'd argue that, at this point, we're getting there in terms of defining complex systems. It's not *only* about non-linear math - but in large part it is the link between that math and the phenomena. The math can describe the behavior of emergent phenomena! that is an amazing thing. And it can derive those dynamics from the micro-level structures below. It's very cool. But it's not just the math - the math is there to describe physical phenomena - specifically, self organization (== emergance). What I'm saying is I'm not sure how you could write a *good* article that talked about these system without bringing in the physical/mathematically based theories of what they are. It would be hand waving - and it's not even necessary. Moreover, I'm not sure that the "field" and the "paradigm" are separate. I think they are the same thing at this point.

I could be wrong, but I don't think the argument follows. I can envisage a linear system that is ill-conditioned, although I don't know if a non-linear system CAN be well posed.

When I originally wrote this, I framed the whole thing with an emphasis on non-linear dynamics.

It always helps to start with a bit of history (George Henry Lewes and Jules-Henri Poincaré) and example like emergent property saltines of salt (NaCl).

Both these terms have multiple meanings in the English language. But as far as technical, scientific meanings go, "complexity" and "complex system" are so close in meaning that they are effectively the same thing. All complex systems exhibit complexity.

I've been working rather intens in this field lately. And much of the work I do is creating the (article) space in such a way that others can further contribute.

Broadly, non-linear does mean dependent on different initial conditions. in simple (one dimensional) non-linear systems, there are only fixed points in the dynamics, to which trajectories will converge. But there can be more than one fixed point, and which one you end up at is determined by initial

Since we are stuck with "complexity", as a concept, we are compelled to use it, but we need to be aware of the fact that "complexity" refers to "methods of description" rather than to nature of natural phenomena. You are right about "complexity" being a (potential) new paradigm in science. But for

The point is that complex systems are described by predictive models that use the maths of non-linear dynamics. Non-linear dynamics itself is not synonymous with complex systems, but it is crucial to their understanding. And not just in describing the components themselves and their interactions;

In respect of all this, I think anyone who wants to chip in on this should read the scholarpedia article (which is *peer* *reviewed*!!!!) I referenced above and look at the bibliography there. Actually, if scholarpedia is GPLed we should probably just copy that article in here (when it is out of

The main reason for so many misunderstandings about complex systems and complexity theory are ambiguous and overcomplicated explanations. People seem to think that words “complexity” and “complex” justify complicated explanations in which even “explanators” (coined word) cannot find their way.

These are good points, well met. But I think it should remain a single article and here's why: What is happening in the field right now is that complex systems has turned into an important branch of physics. The paradigm is best exemplified by Haken and Prigogine. Let's say you wanted to do an

I'm glad you "kind of agree". The extent to which they can be modeled is the extent to which they can be *understood*. The rest is hand waving. It's not science. A model is just a formal explanation. And complex systems *can* be predicted, at least to some extent. I'm not sure why you think a

I just can't see what an article on complex systems that ommitted all theory would have to offer - it might even stoke the fires of confusion in that it would just be a list of "complicated things", which is not the same as a complex system. Morevoer, the scholarpedia article is an excellent

Actually, now that I think about it, two dimensional linear systems have orbits, and the amplitude of the orbit depends on the initial conditions. So that is an example of a linear system that depends on inital conditions. but *qualitatively* the dynamics don;t depend in IC.
