Abstract:
We explain the results recently obtained for the damage-spreading behaviour in the Bak-Sneppen (BS) model (Tamarit et al 1998 Eur. Phys. J. B 1 545). We do this by relating the BS model to a much simpler one, which includes many features of the BS model and provides a clear explanation for the occurrence of power-law growth of the distance.
