Rates of leaps on a landscape combining beneficial and deleterious mutations. Rates of leaps are plotted against the per-genome mutation rate (Lμ) and the leap length for different strengths of selection (A and C: ν|s| = 10; B and D: ν|s| = 100) and for different frequencies of beneficial mutations (A and B: r = 10⁻⁴; C and D: r = 10⁻³). Contour lines indicate orders of magnitude and start from the rate of 10⁻⁵ leaps per generation.
