Constructor Details

WFG

public WFG(int k,
 int l,
 int M)

Constructs a WFG problem instance with the specified number of position-related and distance-related variables and the specified number of objectives.

Parameters:

k - the number of position-related variables defined by this problem

l - the number of distance-related variables defined by this problem

M - the number of objectives defined by this problem

Method Details

newSolution

public Solution newSolution()

Description copied from interface: Problem

Returns a new solution for this problem. Implementations must initialize the variables so that the valid range of values is defined, but typically leave the actual value at a default or undefined state.

Specified by:

newSolution in interface Problem

Returns:

a new solution for this problem
