Description
The attached patch provides:
- mq.SR can now construct PolyBoRi? polynomial systems
- some comments added to pbori.pyx
- BooleanPolynomial.__hash__
- BooleanPolynomial.variables
- coercion of GF(2) elements to BooleanPolynomialRing

Disregard those valgrind results- they are useless.

I think the negative review has been resolved, and the currRing patch attached to this ticket should be applied (given a positive review) soon.

Following Martin's comments on the slowdown caused by using __getattr__ in BooleanPolynomial, attached patch with file name polybori_booleanpolynomial_getattr.patch makes the methods directly available.
Some timings (using random polynomials in each case might not be a good idea, but it still demonstrates the point):
Without the patch:
sage: P = BooleanPolynomialRing(100,'x') sage: from polybori.randompoly import gen_random_poly sage: p = gen_random_poly(int(100)) sage: %timeit s = p.set() 100000 loops, best of 3: 2.85 µs per loop sage: %timeit d = p.deg() 100000 loops, best of 3: 2.26 µs per loop sage: %timeit m = p.lead() 100000 loops, best of 3: 6.7 µs per loop sage: %timeit n = p.navigation() 100000 loops, best of 3: 2.82 µs per loop sage: %timeit c = p.constant() 100000 loops, best of 3: 2.02 µs per loop
With the patch:
sage: %timeit s = p.set() 1000000 loops, best of 3: 540 ns per loop sage: %timeit d = p.deg() 1000000 loops, best of 3: 382 ns per loop sage: %timeit m = p.lead() 100000 loops, best of 3: 3.76 µs per loop sage: %timeit n = p.navigation() 1000000 loops, best of 3: 453 ns per loop sage: %timeit c = p.constant() 1000000 loops, best of 3: 305 ns per loop

attachment:polybori-coercion.patch provides coercion enhancements and small fixes to pbori.pyx. It should be applied after attachment:polybori_booleanpolynomial_getattr.patch.
This patch adds coercion from ZZ, and GF(2) to BooleanPolynomialRing, so Martin's patch needs to be revised.

- Cc burcin added
attachment:polybori-coercion.patch is now ticket #1667.

Replying to burcin:

In the sense that the comments are outdated?
comment:9 Changed 8 years ago by malb
The currRing.patch is now #1701 because it doesn't logically belong here.

Deleted original patch, just use burcin's getattr patch.
comment:11 Changed 8 years ago by mabshoff
- Resolution set to fixed
- Status changed from new to closed
Merged in Sage 2.10.alpha0.
Caution: when patching the offset was very large: Hunk #1 succeeded at 1372 (offset 284 lines). I did verify that indeed the section was moved that far down in the current sources.
Cheers,
Michael
