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.

  • El modelo de Bak-Sneppen es un modelo sencillo de coevolución entre especies interactuantes. Está desarrollado para mostrar cómo la criticalidad autoorganizada puede explicar características claves del registro fósil, como la distribución de medidas de acontecimientos de extinción y el fenómeno de punctuated equilibrio. El nombre se debe en honor a Per Bak y Kim Sneppen. (es)

  • 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. The model dynamics repeatedly eliminates the least adapted species and mutates it and its neighbors to recreate the interaction between species. A comprehensive study of the details of this model can be found in Phys. Rev. E 53, 414–443 (1996). A solvable version of the model has been proposed in Phys. Rev. Lett. 76, 348–351 (1996), which shows that the dynamics evolves sub-diffusively, driven by a long-range memory. 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. (en)

Un estudio comprensible de los detalles de este modelo pueden ser encontrados en Phys. Rev. E 53, 414@–443 (1996). Una versión resoluble del modelo ha sido propuesta en Phys. Rev. Lett. 76, 348@–351 (1996), el cual muestra que la dinámica evoluciona subdifusivamente, conducido por una memoria de gama larga.
