Permuted Mwc random number generator
It is a member of the PCG family but uses an MWC generator instead of an LCG. This an MWC is special form of a MCG generator similar to the PGC-64-fast variant.
Compared to PGC-64-fast, Mwc256XXA64 is both faster and produces higher quality rand numbers (due to using the full 256bit state as opposed to only half of it.)
For a detailed description of the design, see: https://tom-kaitchuck.medium.com/designing-a-new-prng-1c4ffd27124d
Mwc256XXA64
A fast high quality PRNG with 64bits of output, and a 256bit state. This is faster on 64bit architectures.
Mwc128XXA32
A fast high quality PRNG with 32bits of output, and a 128bit state. This is faster on 32bit architectures.
