Bak–Sneppen model

The Bak–Sneppen model is a simple model of co-evolution between interacting species. It was developed to show how self-organized criticality may explain key features of the fossil record, such as the distribution of sizes of extinction events and the phenomenon of punctuated equilibrium. It is named after Per Bak and Kim Sneppen. An evolutionary local search heuristic based on the Bak–Sneppen model, called extremal optimization, has been introduced in Artificial Intelligence 119, 275–286 (2000). The Bak–Sneppen model has been applied to the theory of scientific progress.
