engineering.purdue.edu4 Real Coded GAs Algorithm is simple and straightforward Selection operator is based on the fitness values and any selection operator for the binary-coded GAs can be used Crossover and mutation operators for the real- coded GAs need to be redefined
A FAST ELITIST MULTIOBJECTIVE GENETIC ALGORITHM: NSGA …
web.njit.edupopulation generates ofisprings from crossover and mutation operators, which will be discussed in detail in a later section. The population with the current population and current ofisprings is sorted again based on non-domination and only the best N individuals are selected, where N is the population size.

Regardless of the way crossover is performed, its only outcome is an exchange of genes of parents at certain positions in the chromosome. This means that the first gene in

www.whitman.eduThe mutation operator helps protect against this problem by maintaining diversity in the population, but it can also make the algorithm converge more slowly. Typically the selection, crossover, and mutation process continues until the number of o spring is the same as the initial population, so that the second generation is composed

The initialization procedure usually involve a random creation of solutions. If in a problem the knowl-edge of some good solutions is available, it is better to use such information in creating the initial pop-ulation.
