makeWFG8Function: WFG8 Function

In jakobbossek/smoof: Single and Multi-Objective Optimization Test Functions

WFG8 Function

Description

Eighth test problem from the "Walking Fish Group" problem generator toolkit.

Usage

makeWFG8Function(n.objectives, k, l)

Arguments

n.objectives	[integer(1)] Number of objectives.
k	[integer(1)] Number of position-related parameters. These will automatically be the first k elements from the input vector. This value has to be a multiple of n.objectives - 1.
l	[integer(1)] Number of distance-related parameters. These will automatically be the last l elements from the input vector.

Details

Huband et al. recommend a value of k = 4L position-related parameters for bi-objective problems and k = 2L * (n.objectives - 1L) for many-objective problems. Furthermore the authors recommend a value of l = 20 distance-related parameters. Therefore, if k and/or l are not explicitly defined by the user, their values will be set to the recommended values per default.

Value

[smoof_multi_objective_function] Returns an instance of the WFG8 function as a smoof_multi_objective_function object.
