Reply to Comments on “Simple measure for complexity”

This is the authors' abstract. We don't add key points for this paper.

We respond to the comment by Crutchfield, Feldman, and Shalizi [Comment in this issue, Phys. Rev. E 62, 2996 (2000)] and that by Binder and Perry [preceding Comment, Phys. Rev. E 62, 2998 (2000)], pointing out that there may be many maximum entropies, and therefore "disorders" and "simple complexities." Which ones are appropriate depend on the questions being addressed. "Disorder" is not restricted to be the ratio of a nonequilibrium entropy to the corresponding equilibrium entropy; therefore, "simple complexity" need not vanish for all equilibrium systems, nor must it be nonvanishing for a nonequilibrium system.
