Predictive Models for the Breeder Genetic Algorithm, I: Continuous Parameter Optimization

In this paper a new genetic algorithm called the Breeder Genetic Al gorithm BGA is introduced The BGA is based on arti cial selection similar to that used by human breeders A predictive model for the BGA is presented which is derived from quantitative genetics The model is used to predict the behavior of the BGA for simple test functions Di erent mutation schemes are compared by computing the expected progress to the solution The numerical performance of the BGA is demonstrated on a test suite of multimodal functions The number of function evaluations needed to locate the optimum scales only as n ln n where n is the number of parameters Results up to n are reported
