Self-organized criticality: An explanation of the 1/ f noise
TL;DR: It is shown that dynamical systems with spatial degrees of freedom naturally evolve into a self-organized critical point, and flicker noise, or 1/f noise, can be identified with the dynamics of the critical state.
Journal ArticleDOI
Self-organized criticality
TL;DR: In this article, the authors show that certain extended dissipative dynamical systems naturally evolve into a critical state, with no characteristic time or length scales, and the temporal fingerprint of the self-organized critical state is the presence of flicker noise or 1/f noise; its spatial signature is the emergence of scale-invariant (fractal) structure.

How Nature Works: The Science of Self-Organized Criticality
TL;DR: This chapter discusses the Sandpile Paradigm, Earthquakes, Starquakes, and Solar Flares, and the "Game of Life": Complexity Is Criticality, and Is Life a Self-Organized Critical Phenomenon?
Journal ArticleDOI
Punctuated equilibrium and criticality in a simple model of evolution.
Per Bak,Kim Sneppen +1 more
TL;DR: A simple and robust model of biological evolution of an ecology of interacting species that self-organizes into a critical steady state with intermittent coevolutionary avalanches of all sizes and exhibits ``punctuated equilibrium'' behavior.
