[issue39867] randrange(N) for N's in same dyadic blocs have excessive correlations when sharing identical seeds

2020-03-05 Thread jfbu
jfbu added the comment: "bug" is a strong word, which I did never employ myself, apart from using this channel of report. I rather think of a (non-documented) "deficiency", but I expect the consensus will again be that I am expressing a "raw expression".

2020-03-05 Thread jfbu
jfbu added the comment: @tim.peters yes, a uniform random variable rescaled to two nearby scales N and M will display strong correlations. The CPython randrange() exhibits however orders of magnitude higher such correlations, but only in relation to a common bitlength. A randrange

2020-03-05 Thread jfbu
jfbu added the comment: Yes indeed the source code of _randbelow_with_getrandbits generates this effect. And I understand the puzzlement about my test file setting the same random seed and then complaining about correlations. But there is some non-uniformity which is enormous between what

2020-03-05 Thread jfbu
New submission from jfbu : We generate quadruples of random integers using randrange(n) and randrange(m) and count how many times the quadruples are identical, using the same random seed. Of course for nearby n and m (the real life example was with n==95 and m==97) we do expect matches
