public interface VectorProblem<R>

Interface for vector problems, i.e. problems which have some number of dimensions and each one is bounded.

Method Summary

Modifier and Type	Method and Description
int	dimension() Returns the problem’s dimension.
R	lowerBound(int atDimension) Returns the problem’s lower bound in a given dimension, indexed from 0.
R	upperBound(int atDimension) Returns the problem’s upper bound in a given dimension, indexed from 0.

Method Detail

dimension

int dimension()

Returns the problem’s dimension.

Returns:

the problem’s dimension.

lowerBound

R lowerBound(int atDimension)

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

Parameters:

atDimension - the given dimension

Returns:

the problem’s lower bound in the given dimension

Throws:

java.lang.IllegalArgumentException - if the given dimension is greater than this problem’s one or negative

upperBound

R upperBound(int atDimension)

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

Parameters:

atDimension - the given dimension

Returns:

the problem’s upper bound in the given dimension

Throws:

java.lang.IllegalArgumentException - if the given dimension is greater than this problem’s one or negative
