(A) The density of local fitness maxima ℳ/2^L in a Gumbel-distributed RMF landscape is shown as a function of the number of loci L. Symbols correspond to the large L approximation in Equation 13 and lines to the exact expression in Equation A12. The double-logarithmic scales illustrate that the ratio ℳ/2^L decays algebraically as 1/L for large L. (B) The same quantity for an RMF landscape with a uniformly distributed random component, as given by the exact expressions in Equations A22 and A23. Semilogarithmic scales are used to illustrate the exponential decay of the ratio ℳ/2^L.
