recombination_eigen {ExpDE}

/eigen recombination for DE

Description

Implements the "/eigen" (eigenvector-based) recombination for the ExpDE framework

Usage

recombination_eigen(X, M, recpars)

Arguments

X

population matrix (original)

M

population matrix (mutated)

recpars

recombination parameters (see Recombination parameters for details)

Value

Matrix U containing the recombined population

Recombination Parameters

The recpars parameter contains all parameters required to define the recombination. recombination_eigen() understands the following fields in recpars:

• othername: name of the recombination operator to be applied after the projection in the eigenvector basis

• ... : parameters required (or optional) to the operator defined by recpars$othername
