Implicit knowledge in complex system control What does it take to be a successful manager or politician? In Psychology, tasks that these groups face on an everyday basis are called complex problems. Complex problems are characterized by their dynamics (the system that is being altered during problem solving is constantly changing on its own), by the fact that multiple goals have to be achieved at the same time and by their network structure: changes to one variable usually lead to changes of other variables as well. Experimental Psychology simulates complex problems with computer-simulated dynamic scenarios, also referred to as microworlds; computer games that place the subject into the role of a manager of a factory or a mayor of a small city. Over a simulated period of time, the subject has to improve some target value (e.g. factory profit or item sales) and has a variety of variables that he can change for influencing the system (e.g. number of machines, number of employees, wages, welfare, advertising budget etc). The current state of research argues that it does not require a special skill for complex problem solving, but that complex problem solving ability is determined by a person's intelligence, especially his/her ability to process information, and by a person's knowledge of the problem domain, i.e. structure of the system. However, research has also shown that with longer experience of system control, subjects tend to show better problem solving abilities without showing an increase in verbalizable knowledge. The question whether this was a sign for implicit knowledge or just some artifact has been heavily debated.

43. Complex Systems Conjugate gradient methods for real symmetric systems can be applied to complex Hermitian systems in a straightforward manner. For nonHermitian complex http://www.netlib.org/utk/papers/templates/node82.html

Next: Stopping Criteria Up: Related Issues Previous: Related Issues Complex Systems Conjugate gradient methods for real symmetric systems can be applied to complex Hermitian systems in a straightforward manner. For non-Hermitian complex systems we distinguish two cases. In general, for any coefficient matrix a CGNE method is possible, that is, a conjugate gradients method on the normal equations , or one can split the system into real and complex parts and use a method such as GMRES on the resulting real nonsymmetric system. However, in certain practical situations the complex system is non-Hermitian but symmetric. Complex symmetric systems can be solved by a classical conjugate gradient or Lanczos method, that is, with short recurrences, if the complex inner product is replaced by . Like the BiConjugate Gradient method, this method is susceptible to breakdown, that is, it can happen that for . A look-ahead strategy can remedy this in most cases (see Freund and Van der Vorst and Melissen Jack Dongarra Mon Nov 20 08:52:54 EST 1995

David Jefferies - home pages navigation Simulating Complex Systems Is it possible to simulate engineered complex systems reliably and qualitatively accurately , using deterministic digital computers? It is easy to identify complex systems in the natural world for which simulation fails. We only have to mention turbulent fluid flow, long range weather forecasting, crashes and fluctuations on the world stock markets, and the behaviour of human adversaries in conflict situations. To what extent is it possible to use simulation to design engineered complex systems? For, complexity in engineered systems is increasing rapidly, together with penetration of computing and IT systems into the "combined complex systems", that makes this process of increasing complexity possible. Of course, the computers themselves may be regarded as complex systems. However, we think we have a reasonable grasp of the various kinds of behaviour of digital computer, but even here, catastrophic failures and behaviour that is not qualitatively understood are endemic and frequent. However, in a

The Multiverse According to Ben Tuesday, April 19, 2005 Ben as a Complex System Just a mildly amusing "kids story" today.... I walked into my daughter Zadi's second grade classroom yesterday, to pick her up, and one of the other kids, Caitlyn, pointed at me and said "Zadi's dad: you're complex!" "Well," I said, "I'm made of trillions of little particles, but so are you we're all complex..." "YOU'RE complex!" "Well, hmmm.... Why do you think so?" She laughed. "Zadi said her dad is complex." "Well YOU're silly!" Apparently they were studying the word "complex" at school and the kids were asked to give an example of something complex. Zadi suggested her dad. I asked her later if she could think of anything more complex than me; her reply: "the universe is one example".... posted by Ben at 8:14 PM 4 Comments: said...

Mantegna (Submitted on 14 Nov 2001 ( ), last revised 3 Jun 2003 (this version, v2)) Abstract: We study the relaxation dynamics of a financial market just after the occurrence of a crash by investigating the number of times the absolute value of an index return is exceeding a given threshold value. We show that the empirical observation of a power law evolution of the number of events exceeding the selected threshold (a behavior known as the Omori law in geophysics) is consistent with the simultaneous occurrence of (i) a return probability density function characterized by a power law asymptotic behavior and (ii) a power law relaxation decay of its typical scale. Our empirical observation cannot be explained within the framework of simple and widespread stochastic volatility models. Comments: 4 pages,4 figures, accepted in PRE

Tuesday, May 23, 2006 Features of Analyzing Complex Social Systems: Individuals vs Superorganism In Yaneer Bar-Yam's textbook " Dynamics of Complex Systems " (1997), the final chapter considers looking at complex social systems, i.e. civilizations. There have been numerous posts around the blogosphere in the past few months that have been focused on issues involving complex systems network theory emergence resilience ... consilience , and so on, as they apply to a variety of systems, both physical and social, including a number on this blog. One aspect of these types of analyses that has been overlooked is the role of the individual within the collective system, and this is precisely what Bar-Yam warns against. A term that has arisen within biology, the " superorganism Placing more of an emphasis on the business sector in economic/fiscal policy, for instance, seems to be focused more on the superorganism. Big business is a sort of faceless, complex system in its own right, and one type of policy can be derived from this perspective. Placing an emphasis on how it affects individuals who make up the system, such as the poor and middle class (i.e. the average, individual citizen), leads to a separate approach for fiscal policy. Proponents of gun control laws, on the other hand, seem to be looking more closely at the superorganism, while those who are against gun control laws seem to focus more on individuals within the system. Interestingly, political parties such as the Republicans and Democrats may swap which perspective they take toward policy-making in these two examples.

This paper searches for a useful taxonomy or classification scheme for complex Systems. There are two aspects to this problem: 1) distinguishing between Engineering Systems (the term we use) and other Systems, and 2) differentiating among Engineering Systems. Engineering Systems are found to be differentiated from other complex systems by being human-designed and having both significant human complexity as well as significant technical complexity. As far as differentiating among various engineering systems, it is suggested that functional type is the most useful attribute for classification differentiation. Information, energy, value and mass acted upon by various processes are the foundation concepts underlying the technical types.

News New Journals Browse Journals Search ... ACS Advances in Complex Systems (ACS) A Multidisciplinary Journal Advances in Complex Systems aims to provide a unique medium of communication for multidisciplinary approaches, either empirical or theoretical, to the study of complex systems. The latter are seen as systems comprised of multiple interacting components, or agents. Nonlinear feedback processes, stochastic influences, specific conditions for the supply of energy, matter, or information may lead to the emergence of new system qualities on the macroscopic scale that cannot be reduced to the dynamics of the agents. Quantitative approaches to the dynamics of complex systems have to consider a broad range of concepts, from analytical tools, statistical methods and computer simulations to distributed problem solving, learning and adaptation. This is an interdisciplinary enterprise.
