Talk:complex system

The request for verification on the three definitions of complex system

 * The folowing discussion is copied from the request for verification talk page

Definition 1 seems to be sum of parts. Definitions 2 and 3 seem to refer to complexity not complex system. SemperBlotto 07:22, 22 August 2007 (UTC)


 * I'm just in the process of rewritting the complex system article on Wikipedia, and talking about this on the talk page. The definitions I stated here in Wiktionairy are the assumption I made there. They are just like the definitions I recently stated here about systems theory and systems engineering.


 * The thing is that in the field of systems theory some of the essential terms (like I just brought in) are not well defined. The defintions I gave are ment as a codification: An attempt to define the field. Now I haven't verified those definitions. And I'm not sure what you ment by verfification of terms used in a cloudy field? I'm depending here on my own experiences, that this field is in need of clear definitions.


 * But you asking for verification of the meanings of complex systems.
 * first a special kind of system
 * second a paradigm
 * third a field of science
 * Now you agree with the first.
 * The second definition can be found in the recent scholarpedia article, see . The article is called complex system and starts with complexity. The autor presumes here that those two are the same. Otherwise they would have called the whole article complexity.
 * About the third definition we had a mayor discussion around the renaming of the Wikipedia category complex systems to complex systems theory. I would like to give the question back here. Where did you get the idea that they call the whole field complexity and not complex systems? I believe you that there are authors naming the field the one and the other. But explicitely complexity and not complex systems? - Mdd 12:05, 22 August 2007 (UTC)


 * On second thought SemperBotto is (probably partly) right: The specific field of science and the paradigm are called complexity... and they are also called complex systems. But on the other hand an expert in the field told me yesterday. : ... But as far as technical, scientific meanings go, "complexity" and "complex system" are so close in meaning that they are effectively the same thing.


 * I guess a thing I can do now is, create an article complex systems here, with cross references to complex system and complexity!? - Mdd 08:30, 23 August 2007 (UTC)

 * Current definition is unusable. Wikipedia's article says "A complex system is a system composed of interconnected parts that as a whole exhibit one or more properties ... not obvious from the properties of the individual parts", which may be of encyclopaedic interest but doesn't seem interesting to us.

 * Looks to me like the contributor accidentally hit save while writing the definition, therefore leaving it unfinished! Delete (or even speedy delete) or come up with a definition that's in comprehensible English. Mglovesfun (talk) 11:18, 6 October 2010 (UTC)
 * Delete OneLook coverage is either definitionless or encyclopedic. Suggestively, if not conclusively, stress is on "system", not "complex" in normal speech. I could imagine the opposite only in a context-specific effort to establish a contrast, as when making a nonce definition in a scholarly work. DCDuring TALK 15:05, 6 October 2010 (UTC)


 * Delete Already been at rfv with previous consensus to delete. TeleComNasSprVen 21:22, 8 October 2010 (UTC)
 * Keep the entry, rewrite the definition. The current definition "specific kind of system, which a certain complexity" seems wrong. The current definition really seem sum-of-partish, but I suspect there is a definition that is not. The argument that Wikipedia's definition is encyclopedic is unconvincing to me: definitions are dictionary material. Possibly, a "complex system" does not need to be particularly complex in that it may consist of only a few parts and a few couplings between the parts; it may show complex behavior instead. This would require some research. Unfortunately, we have no quotations in the entry. --Dan Polansky 10:09, 11 October 2010 (UTC)

deleted. Even German Wikipedia says "A complex system is a system that is complex." -- Prince Kassad 13:50, 5 April 2011 (UTC)
