Abstract :
This paper experimentally investigates the effect of global recombination operators on multirecombination Evolution Strategies ((μ/ρ,λ)-ES). For ES, each individual has a pair of real-valued vectors, i.e., object parameters and strategy parameters. We adopt two popular global recombination operators, namely Global Intermediate Recombination (GIR) and Global Discrete Recombination (GDR), and apply GIR or GDR to both object parameters and strategy parameters. Computer simulations are conducted using three types of (μ/μ,λ)-ES, which are Classical-ES (CES), Fast-ES (FES) and Robust-ES (RES). We show the advantages of GIR or GDR in CES, FES and RES. Especially, GDR on a pair of an object parameters and a strategy parameters improves the performance of all ESs in our experiments
