“…The use of more than one objective seems to be a more realistic strategy and, despite of not having produced hypothetical codes identical to the canonical code, the results encourage us to search for new properties that may have been important during the evolutionary process of the canonical genetic code. One of the objectives that will be investigated in the proposed Pareto approach will be entropy [ 30 ].…”

“…Hence, the restrictive encoding uses information in the standard code to generate hypothetical codes. On the other hand, as described in [30], the use of this information avoids the main problem with the non-restrictive encoding, that is: the best hypothetical codes are those where almost all of the codons are associated with a few amino acids and most amino acids are associated with only one codon.…”

“…It is also important to observe that, intuitively, the most robust codes are those where most codons are associated with the amino acids that are most important for minimizing Eq. 1, i.e., those with the shortest mean distances to all others [30]. For this reason, when using a non-restrictive encoding in a single objective algorithm, the frequencies of some amino acids increase too much, while the frequencies of some amino acids remain too small.…”

“…Em [OLIVEIRA;TINÓS, 2014], além de uma medida de robustez, considera-se também a entropia do código genético. Já em [OLIVEIRA et al, 2015] e [OLIVEIRA et al, 2017], utilizam-se duas ou três medidas de robustez baseadas em diferentes propriedades dos aminoácidos.…”

“…é dada pelo erro médio quadrático de todas as alterações possíveis na propriedade dos aminoácidos. A somatória é ponderada por um termo que leva em consideração a posição do nucleotídeo[OLIVEIRA & TINÓS, 2014]. A robustez do código em relação à propriedade X pode ser entendida como o inverso do erro médio quadrático dado na Eq.…”
