Abstract
We study the behavior under perturbations in the, recently introduced, Bak-Sneppen model with deterministic updating. We focus our attention on the damage-spreading features and show that the value of the growt h exponent for the distance, alpha = 0.32, coincides with that of the random updating Bak Sneppen model. Moreover, we generalize this analys is by considering a broader set of initial perturbations for which the value of alpha is preserved.
