Some experimental observations of (μ/μ,λ)-evolution strategies

The multi-recombinant (μ/μ,λ)-evolution strategy (ES) is investigated on a set of real-valued test functions empirically, in order to obtain guidelines for choosing a potential type of recombination in the framework of ESs. Applying the multi-parent versions of intermediate recombination (μ/μ_I,λ) and discrete recombination (μ/μ_D,λ) to both objective variables and strategy parameters, five ESs with different recombination mechanisms are adopted. It has been found that, in most cases, robust performance can be obtained when discrete recombination is applied simultaneously to an object variable-strategy parameter pair
