All Implemented Interfaces:
RandomLongGenerator, RandomNumberGenerator, LinearCongruentialGenerator, Seedable
public class MRG extends Object implements LinearCongruentialGenerator
A Multiple Recursive Generator (MRG) is a linear congruential generator which takes this form: 

 xi = (a1 * xi-1 + a2 * xi-2 + ... + ak * xi-k) mod m
 ui = xi / m
