WFG8 function

The WFG8 test function.

WFG8(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

Returns

A matrix of size nObjective, containing the objective values.

Examples

individual <- runif(14)
nObj <- 4
WFG8(individual,nObj)
