self-organized criticality

(physics)
Property of a system that persistently operates far from equilibrium, at or near a threshold of instability, having evolved automatically to this critical state independently of external fields.

Bak refers to this critical state as a state of self-organized criticality (SOC), since the sand grains on the surface of the sand pile have self-organized to a point where they are just barely stable.
Numerical and analogue modelling of magma segregation has revealed a self-organized criticality phenomenon of the partial melting system.
The researchers claim to have identified a mechanism called self-organized criticality, where systems spontaneously organize themselves to operate at a critical point between order and randomness.
(2006), the authors use an elementary, agent-based model in the spirit of models applied to understanding self-organized criticality. (8) Physicists have used these models to study cascading phenomena in a variety of systems (for instance, Jensen [1998]), where models made of very simple agents, interacting with neighboring agents, can yield surprising insights about system-level behavior.
These characteristics of self-organizing systems can be extended to P2P systems establishing several basic criteria such as boundaries, reproduction, mutability, organization, metrics and adaptivity; and criteria for autonomy as feedback, reduction o complexity, randomness, self-organized criticality and emergence.
In such a context--who knows?--economic theory might well benefit from the consideration of "self-organized criticality" and/or "complex adaptive systems theory."
The motivation behind this approach was to test whether or not differing geographical fault layouts could account for the occurrence of discontinuous or continuous behavior called Self-Organized Criticality. Our data shows that varying fault layouts do indeed affect the discontinuous versus continuous nature of the earthquake energy release of a fault system.
