Description (last modified by fredrik.johansson)

This adds "arb" as an algorithm and makes it the default since it is faster (and provably correct modulo bugs).


sage: %timeit hilbert_class_polynomial(-103, algorithm="arb");
10000 loops, best of 3: 74.9 µs per loop
sage: %timeit hilbert_class_polynomial(-103, algorithm="sage");
1000 loops, best of 3: 1.13 ms per loop

sage: %time a=hilbert_class_polynomial(-10000003, algorithm="arb");
CPU times: user 24.4 s, sys: 43.9 ms, total: 24.4 s
Wall time: 24.4 s
sage: %time b=hilbert_class_polynomial(-10000003, algorithm="sage");
CPU times: user 5min, sys: 509 ms, total: 5min 1s
Wall time: 5min 1s
sage: a == b

This branch includes a commit from #20031 since I added acb_modular.pxd there. I guess it would be cleanest to wait for #20031 before merging this.

New commits:

7552190Upgrade arb to version 2.8.1
c57d86fupgrade doctests to reflect precision changes in latest arb
5993a34fix ComplexBallField element raised to negative Python int
