title: Comment on "1/f noise in the Bak-Sneppen model".
abstract: Contrary to the recently published results by Daerden and Vanderzande [Phys. Rev. E 53, 4723 (1996)], we show that the time correlation function in the random-neighbor version of the Bak-Sneppen model can be well approximated by an exponential giving rise to a 1/f(2) power spectrum.
