On the choice of the parameter control mechanism in the (1+( λ, λ )) genetic algorithm
Mario Alejandro Hevia Fajardo, Dirk Sudholt · 2020
The self-adjusting (1 + (λ, λ)) GA is the best known genetic algorithm for problems with a good fitness-distance correlation as in OneMax. It uses a parameter control mechanism for the parameter λ that governs the mutation strength and the number of offspring. However, on multimodal problems, the parameter control mechanism tends to increase λ uncontrollably.
