The scheme of the crossover operator for the BS model. a Amino acids of the parental code P1 are selected randomly and assigned to the corresponding codon blocks in the offspring O1. Similarly, amino acids of the parental code P2 are also selected randomly and assigned to the corresponding codon blocks in the offspring O2. b The consecutive amino acids of P1 are selected one by one and assigned to the remaining codon blocks in O2. Similarly, the consecutive amino acids of P2 are also selected one by one and assigned to the remaining codon blocks in O1. When an amino acid is already present in the offspring, the next one in the amino acid set is selected
