Genetic algorithm randomly reforms the important gene of code bunch to optimize the new individual bunch and make individual evolve continuously to get optimization result.
Genetic algorithm establishes an iterative process in which genetic algorithm substitutes code space for parameter space, applies fitness function as evaluation standard, takes code space as evolutionary basis, realizes selective and genetic mechanism by genetic operation on individual bunch. It randomly reforms the important gene of code bunch to optimize the new individual bunch and make individual evolve continuously to get optimization result.
