چکیده

A self-adaptation of arbitrary normal mutation distributions within the concept of muta-tive strategy parameter control (MSC) using a newly formulated mutation operator is introduced. The coordinate system independent formulation ensures the invariance of the algorithm towards arbitrary linear transformations , which is a novelty for self-adaptation within the concept of MSC. To enable a sensible adaptation, the population size must scale quadratically with the problem size N { according to the number of adapted strategy parameters. Because the adaptation time (number of generations) also scales with N 2 , the overall adaptation expense amounts to N 4 function evaluations.

Completely Derandomized Self-Adaptation in Evolution Strategies

This paper puts forward two useful methods for self-adaptation of the mutation distribution - the concepts of derandomization and cumulation. Principle shortcomings of the concept of mutative strategy parameter control and two levels of derandomization are reviewed. Basic demands on the self-adaptation of arbitrary (normal) mutation distributions are developed. Applying arbitrary, normal mutati...

Adapting Arbitrary Normal Mutation Distributions in Evolution Strategies: The Covariance Matrix Adaptation

|A new formulation for coordinate system independent adaptation of arbitrary normal mutation distributions with zero mean is presented. This enables the evolution strategy (ES) to adapt the correct scaling of a given problem and also ensures invariance with respect to any rotation of the tness function (or the coordinate system). Especially rotation invariance, here resulting directly from the ...

On the Adaptation of Arbitrary Normal Mutation Distributions in Evolution Strategies: The Generating Set Adaptation

A new adaptation scheme for adapting arbitrary normal mutation distributions in evolution strategies is introduced. It can adapt correct scaling and correlations between object parameters. Furthermore, it is independent of any rotation of the objective function and reliably adapts mutation distributions corresponding to hyperellipsoids with high axis ratio. In simulations, the generating set ad...

A Derandomized Approach to Self Adaptation of Evolution Strategies

Comparable to other optimization techniques, the performance of Evolution Strategies (ESs) depends on a suitable choice of internal strategy control parameters. Apart from a xed setting, ESs facilitate an adjustment of such parameters within a selfadaptation process. For step-size control in particular, various adaptation concepts have been evolved early in the development of ESs. These algorit...
