%0 Journal Article %T Asymptotic fitness distribution in the Bak-Sneppen model of biological evolution with four species %A Eckhard Schlemm %J Quantitative Biology %D 2012 %I arXiv %R 10.1007/s10955-012-0538-2 %X 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. %U http://arxiv.org/abs/1207.0108v1
