recombination_npoint {ExpDE}

n-point recombination for DE

Description

Implements the "/npoint" (n-point) recombination for the ExpDE (as used in the Simple GA).

Usage

recombination_npoint(X, M, recpars = list(N = NULL))

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_npoint() understands the following fields in recpars:

• N : cut number points for crossover.
  Accepts integer value 0 <= N < n, where n is the dimension of the problem; Use N = 0 or N = NULL for randomly choosing a number of cut points.
  Defaults to NULL.
