Adaptive Tension Systems: Towards a Theory of Everything? Heikki Hyötyniemi Helsinki University of Technology Control Engineering Laboratory P.O. Box 5500, FIN-02015 TKK, Finland Abstract Assuming that there really exists some general theory of complex systems, one has strong guidelines for where to search for it. Such theory has to address the distributedness of the underlying actors in the absence of central control, and it has to explain emergence in terms of self-regulation and some kind of self-organization of higher-level structures. It is the neocybernetic framework of Adaptive Tension Systems (also known as “elastic systems”) that is one candidate theory offering such visions, making it possible to make assumptions about the “Platonian Ideals” of complex interacting systems. As application examples, this methodology is here employed for analysis of molecular orbitals and orbiting mass systems. 1 Introduction all of them: They all consist of distributed networks where local-level interactions of more or less mind- It is intuitively clear that there is something in com- less actors with only very simple functionalities result mon beyond different kinds of complex systems — in self-regulation and self-organization that is visi- is it not?
