Asymptotic Fitness Distribution in the Bak-Sneppen Model of Biological Evolution with Four Species

Abstract

We suggest a new method to compute the asymptotic fitness distribution in the Bak-Sneppen model of biological evolution. As applications we derive the full asymptotic distribution in the four-species model, and give an explicit linear recurrence relation for a set of coefficients determining the asymptotic distribution in the five-species model. © 2012 Springer Science+Business Media, LLC.
