WFG9: The WFG9 test function.

In MaOEA: Many Objective Evolutionary Algorithm

Description

The WFG9 test function.

Usage

WFG9(individual, nObj, k = nObj - 1)

Arguments

individual	The individual to be evaluated, the search space should be in [0-2i] for variable number i. Can accept multiple individualm each in different column.
nObj	The number of objective
k	Number of distance related parameters. The reference suggests a positive integer multiplied by (nObj-1). Default to nObj-1

Value

A matrix of size nObjective, containing the objective values.
