WebFlip mutation is a type of mutation used with binary crossover, in which a randomly selected bit of the chromosome is flipped. Swap mutation is a kind of mutation where two randomly selected genes have their alleles swapped. Random initialization is used to re-initialize the discrete values/integers of a gene with a random value from a given range. WebJul 15, 2024 · There are different types of mutation such as bit flip, swap, inverse, uniform, non-uniform, Gaussian, shrink, and others.
