Respite32Random is a 32-bit-native generator here that doesn't have any shorter subcycles (because it only has one
cycle, of length 2 to the 96).
A wrapper around a different
EnhancedRandom object that runs it in reverse, calling
EnhancedRandom.previousLong() instead anywhere ReverseWrapper.nextLong() would be called.A well-studied RNG that can be quite fast in some circumstances.
A generator with 4
long states and a guaranteed minimum period of 2 to the 64, this is structured much like

minimum period, and uses only add, bitwise-rotate, and XOR operations (no multiplication).
Not actually a pseudo-random number generator, but a quasi-random number generator, this is a fairly simple
way to produce values that have some advantages of quasi-random numbers, but works better in some cases than
