This pseudorandom number generator (PRNG) is a linear congruential pseudorandom number generator (LCG) whose output is shuffled using the Bays- Durham algorithm. The shuffle step considerably strengthens the "randomness quality" of a simple LCG's output.
The generator has a period of approximately 2.1e9.
An LCG is fast and uses little memory. On the other hand, because the generator is a simple LCG, the generator has recognized shortcomings. By today's PRNG standards, the generator's period is relatively short. In general, this generator is unsuitable for Monte Carlo simulations and cryptographic applications.
