The _advance function in this prng is also way too weak, purely linear with a tiny bit of output mixing. Replacing self.state with the (64-bit) result of the xo

The _advance function in this prng is also way too weak, purely linear with a tiny bit of output mixing. Replacing self.state with the (64-bit) result of the xorshifts would help a lot.

Are you claiming that PCG is a bad pseudorandom number generator? If so, you are mistaken

  Yes, I predict it will fail most of the DieHard tests.

    I like your murmur work, but you're getting it wrong today

      Getting it wrong is part of the job.

        Agreed. No one should hold it against you But we have to be careful about claiming that a generator is unreliable. PRNGs are very susceptible to rumor and uncertainty and doubt, because almost nobody understands them
