recombination_pbest {ExpDE}

p-Best recombination for DE

Description

Implements the "/pbest" (p-Best) recombination for the ExpDE framework

Usage

recombination_pbest(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_pbest() understands the following fields in recpars:

• cr : component-wise probability of using the value in M.
  Accepts numeric value 0 < cr <= 1.

Warning

This routine will search for the iterations counter (t), the maximum number of iterations (stopcrit$maxiter), and the performance vector of population X (J) in the parent environment (using parent.frame(). These variables must be defined for recombination_pbest() to work.
