Add Randomizations from Redzen package as initial step to implement #60 #69

Closed rafalkozik closed 3 years ago

rafalkozik commented 4 years ago

First step to implement enhancement from #60 is to add Randomization from Redzen package and check how they perform against bundled FastRandom

colgreen commented 3 years ago

I recommend Xoshiro256StarStarRandom, i.e., this one:

https://github.com/colgreen/Redzen/blob/master/Redzen/Random/Xoshiro256StarStarRandom.cs

In the Redzen project I have marked XorShiftRandom as obsolete, as the above implementation is an evolution of that original PRNG created by George Marsaglia, and passes far more statistical tests. For more info see:

http://prng.di.unimi.it/

And I totally understand the desire to minimise dependencies on external nuget packages - it's a slippery slope to complex package management issues/pain.
