public class CellularAutomatonRNG extends Random implements RepeatableRNG
Java port of the cellular automaton pseudorandom number generator developed by Tony Pasqualoni.
NOTE: Instances of this class do not use the seeding mechanism inherited from
Random
. Calls to theRandom.setSeed(long)
method will have no effect. Instead the seed must be set by a constructor.- See Also:
