Phys. Rev. E 63, 063101 (2001) [2 pages]Comment on “1/f noise in the Bak-Sneppen model”Received 18 August 2000; published 24 May 2001 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/f2 power spectrum. © 2001 The American Physical Society URL:
