Stanford Seminar PCG: A Family of Better Random Number Generators - The Best Documentary Ever.How Random Is Your RNG [ShmooCon 2015]. A permuted congruential generator (PCG) is an pseudorandom number generation algorithm developed in 2014 which applies an output permutation function to improve the statistical properties of a modulo-2n linear congruential generator. Ecuyers WELL family of generators is considered by some superior to the Mersenne-Twister, although these generators do fail the Matrix rank test for high PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. In any case, many programmers have now adopted a new random number generator called PCG and designed by professor Melissa ONeill from Harvey Mudd college. What ONeill did is quite reasonable. Whats Wrong with Your Current RNG Most random number generators in widespread use today have one of the following problems: Not Actually Random BehavingTo explain why the PCG family is better, we need to get a little bit technical. There are two parts to a random number generator. PCG is a family of simple fast space-efficient statistically good algorithms for random number generation.Whats Wrong with Your Current RNG. Most random number generators in widespread use today have one of the following problems Generate a random number in [0,bound). This function corresponds to pcg32boundedrandr and can call the random-number generator more than once.

Click More random numbers to generate some more, click customize to alter the number ranges (and text if required). However if you are using a random number generator in a high security environment then it becomes very important.I dont know if PCG will live up to its claim. The first test will be if the paper is accepted and then how many people cite that paper. Make a random number engine pcg32 rng(seedsource)pcgextras::seedseqfrom is supposed to be the recommended way, but it delegates the actual seed generation to the generator specified in the template parameter.
