ParallelProblem

public ParallelProblem(int dimension,
                       R min,
                       R max)

Creates a ParallelRoblem with a range of [min, max] and a given dimension.

Parameters:

dimension - This problem dimension

min - This problem lower bound

max - This problem upper bound

Method Detail

dimension

public final int dimension()

Description copied from interface: VectorProblem

Returns the problem’s dimension.

Specified by:

dimension in interface VectorProblem<R>

Returns:

the problem’s dimension.

lowerBound

public final R lowerBound(int atDimension)

Description copied from interface: VectorProblem

Returns the problem’s lower bound in a given dimension, indexed from 0. It must be not greater than the VectorProblem.upperBound(int) in the same dimension.

Specified by:

lowerBound in interface VectorProblem<R>

Parameters:

atDimension - the given dimension

Returns:

the problem’s lower bound in the given dimension

upperBound

public final R upperBound(int atDimension)

Description copied from interface: VectorProblem

Returns the problem’s upper bound in a given dimension, indexed from 0. It must be not smaller than the VectorProblem.lowerBound(int) in the same dimension.

Specified by:

upperBound in interface VectorProblem<R>

Parameters:

atDimension - the given dimension

Returns:

the problem’s upper bound in the given dimension

checkDimension

private void checkDimension(int atDimension)
