Optimal Restart Strategies for Parameter-dependent Optimization Algorithms
Lisa Schönenberger, Hans-Georg Beyer
This paper examines restart strategies for algorithms whose successful termination depends on an unknown parameter . After each restart, is increased, until the algorithm…
On the Interaction of Adaptive Population Control with Cumulative Step-Size Adaptation
Amir Omeradzic, Hans-Georg Beyer
Three state-of-the-art adaptive population control strategies (PCS) are theoretically and empirically investigated for a multi-recombinative, cumulative step-size adaptation Evolut…
Mutation Strength Adaptation of the -ES for Large Population Sizes on the Sphere Function
Amir Omeradzic, Hans-Georg Beyer
The mutation strength adaptation properties of a multi-recombinative -ES are studied for isotropic mutations. To this end, standard implementations of cumulative ste…
Analyzing design principles for competitive evolution strategies in constrained search spaces
Michael Hellwig, Hans-Georg Beyer
In the context of the 2018 IEEE Congress of Evolutionary Computation, the Matrix Adaptation Evolution Strategy for constrained optimization turned out to be notably successful in t…
