Hmm, I guess that makes sense. I tried to adjust my algorithms to do the same
thing with the same bit

I tried to implement a different implementation of the ziggurat method for
generating standard normal distributions that is about twice as fast and uses
2/3 of the memory than the old one.
I tested the implementation separately and am very confident it's correct, but
it does fail 28 test in cove
Have you benchmarked it using the generator interface? The structure of
this as a no monolithic generator makes it a good deal slower than
generating in straight C (with everything inline). While I'm not sure a
factor of 2 is enough to justify a change (for me 10x, 1.2x is not but I
don't know whe
Well, I can tell you why it needs to be backward compatible! I use random
numbers fairly frequently, and to unit test them I set a specific seed and
then make sure I get the same answers.
If your change went in (and I were using numpy normal distributions, which
I am not) then my tests would brea
