Figure 9From: Evolution of the genetic code: partial optimization of a random code for robustness to translation error in a rugged fitness landscapeEvolution of codes in a rugged fitness landscape (a cartoon illustration).r1, r2 ∈ r: random codes with the same block structure as the standard code. o1, o2 ∈ o: codes obtained from r1, r2 ∈ r: after optimization. R1, R2 ∈ R: random codes with fitness values greater than the fitness of the standard code. O1, O2 ∈ O: codes obtained from R1, R2 ∈ R: after optimization.Back to article page
