preset_moead: preset_moead

In MOEADr: Component-Wise MOEA/D Implementation

preset_moead

Description

Generate a preset configuration for moead()].

Usage

preset_moead(name = NULL)

Arguments

name	name of the preset to be generated. Use preset_moead() to obtain the list of available options.

Details

This function returns a list of configuration presets taken from the literature to be used with the moead() function in package MOEADr.

Use these configurations as a starting point. We strongly recommend that you play around with the particular configurations (see example).

Value

List object containing the preset, to be used as an input to moead(); or, if name == NULL (the default), returns a logical flag invisibly.
