perform_variation {MOEADr}

Run variation operators

Description

Sequentially apply variation operators for the MOEADr package

Usage

perform_variation(variation, X, iter, ...)

Arguments

variation

List vector containing the variation operators to be used. See moead() for details.

X

Population matrix of the MOEA/D (each row is a candidate solution).

iter

iterations counter of the moead() function.

...

other parameters to be passed down to the individual variation operators (see documentation of the specific variation_xyz⁠()⁠ functions for details)

Details

This routine performs the variation block for the MOEA/D. The list of available variation operators can be generated using get_variation_operators().

If the localsearch operator is included, it is executed whenever its conditions (period of occurrence or probability of occurrence) are verified. See variation_localsearch() for details.

Value

List object containing a modified population matrix X, a local search argument list ls.arg, and the number of function evaluations used by the variation operators, var.nfe.
