public class KorobovLattice
This class implements Korobov lattices, which represents the same point
sets as in class LCGPointSet, but implemented differently.
The parameters are the modulus n and the multiplier a, for an arbitrary
integer
1 <= a < n. [When a is outside the interval [1, n), then we
replace a by (a mod n) in all calculations.]
The number of points is n, their dimension is
s, and they are defined by
It is also possible to build a ``shifted'' Korobov lattice with the first t coordinates rejected. The s-dimensionnal points are then defined as
