Figure 2From: The effect of genetic robustness on evolvability in digital organismsA) Rate of adaptation as a function of mutation rate for a more complex, 77-task, environment (white: fragile genotype F ; black: robust genotype R ). B) Fitness versus time for lineages evolved from F (red) and R (blue) in this environment at a mutation rate U = 1. Fitness was calculated in the same manner as in Fig. 1.Back to article page
