Detailed Description

template<class TIndividual>
class FREE::ES::CMAMutation< TIndividual >

Mutation component of an ES.

Mutates the objective values by using a global covariance matrix. The covariance matrix is adapted by using the centroid of a selection of the actual population and comparing it with the centroid of the last generation. The step size will be adapted by evaluating the evaluation path. For more information see references: [1] Hildebrand, L.: Asymmetrische Evolutionsstrategien, In Fachbereich Informatik. 2002, Universität Dortmund: Dortmund, Germany. p. 300.
