computeHammingDistance method

num computeHammingDistance(covariant Phenotype<G, R> other)

Returns the degree to which this chromosome has dissimilar genes with the other. If chromosomes are identical, returns 0.0. If all genes are different, returns 1.0.

Genes are considered different when they are not equal. There is no half-different gene (which would make sense for num genes, for example). You should make sure genes have sane equality and hashCode.

Implementation

num computeHammingDistance(covariant Phenotype<G, R> other) {
  var length = genes.length;
  var similarCount = 0;
  for (var i = 0; i < genes.length; i++) {
    if (genes[i] == other.genes[i]) {
      similarCount++;
    }
  }
  return (1 - similarCount / length);
}
