Old description:
> Some improvements for the affine factorization crystal.
New description:
This patch provides some improvements for the affine factorization
crystal.
Before this patch
{{{
sage: from sage.combinat.crystals.affine_factorization import
AffineFactorizationCrystal
sage: W = WeylGroup(['A',3], prefix='s')
sage: w0 = W.long_element()
sage: %timeit B = AffineFactorizationCrystal(w0,6)
1 loops, best of 3: 131 s per loop
}}}
After this patch
{{{
sage: from sage.combinat.crystals.affine_factorization import
AffineFactorizationCrystal
sage: W = WeylGroup(['A',3], prefix='s')
sage: w0 = W.long_element()
sage: %timeit B = AffineFactorizationCrystal(w0,6)
1 loops, best of 3: 2.86 us per loop
}}}
