WebJul 10, 2024 · Random Selection, a way to randomly choose pairs of chromosomes from parents without the effect of fitness values. More simply, it just needs to generate random values to select the index as the parent chromosome. Tournament selection, this selection method makes a selection based on fitness values. WebA chromosome is composed of a set of genes, where a gene consists of one or more semantically connected parameters, which are often also called decision variables. They determine one or more phenotypic characteristics of the individual or at least have an influence on them. [2]
