public class MultiplyWithCarryGenerateRandom
extends AbstractBoxMuller

In Multiply with Carry (MWC) is a pseudo random number generator computer science, multiply-with-carry (MWC) is a method invented by George Marsaglia for generating sequences of random integers based on an initial set from two to many thousands of randomly chosen seed values. The main advantages of the MWC method are that it invokes simple computer integer arithmetic and leads to very fast generation of sequences of random numbers with immense periods. This class was implemented using information from the following sources:
