Description (last modified by )
In order to speed up many of the crystals computations, I'm proposing the following:
- Cythonize
CrystalOfLetters
- Make
index_set()
a cached method. Subsequently this requires it to be returned as a tuple instead of a list - Make different letters classes, one for integers (classical types), one for tuples (exceptional/spin)
- Store by caching result of
_element_constructor_()
the elements ofCrystalOfLetters
.
See #14686 for a followup.

I'm also getting significant speedups now in creating CrystalOfLetters
and doctests for tensor_product.py
and kirillov_reshetikhin.py
:
sage: %time C = CrystalOfLetters(['D',100]) CPU times: user 0.84 s, sys: 0.24 s, total: 1.08 s Wall time: 1.67 s sage -t tensor_product.py [349 tests, 13.05 s] sage -t kirillov_reshetikhin.py [653 tests, 30.51 s]
Before:
sage: %time C = CrystalOfLetters(['D',100]) CPU times: user 2.33 s, sys: 0.42 s, total: 2.76 s Wall time: 3.58 s sage -t tensor_product.py [349 tests, 14.60 s] sage -t kirillov_reshetikhin.py [653 tests, 47.96 s]

I'll upload the split patch shortly and check to see if it can commute pass #14143.

With patch:
sage: %time C = CrystalOfLetters(['D',100]) CPU times: user 1.54 s, sys: 0.03 s, total: 1.56 s Wall time: 1.72 s sage: B = InfinityCrystalOfTableaux(['B',3]) sage: S = B.subcrystal(max_depth=4) sage: %time G = B.digraph(subset=S) CPU times: user 28.20 s, sys: 0.03 s, total: 28.23 s Wall time: 28.62 s sage: C = CrystalOfTableaux(['D',4], shape=[2,1]) sage: %time G = C.digraph() CPU times: user 0.33 s, sys: 0.00 s, total: 0.34 s Wall time: 0.34 s
Before:
sage: %time C = CrystalOfLetters(['D',100]) CPU times: user 1.84 s, sys: 0.02 s, total: 1.86 s Wall time: 2.00 s sage: B = InfinityCrystalOfTableaux(['B',3]) sage: S = B.subcrystal(max_depth=4) sage: sage: %time G = B.digraph(subset=S) CPU times: user 28.96 s, sys: 0.03 s, total: 28.99 s Wall time: 29.94 s sage: C = CrystalOfTableaux(['D',4], shape=[2,1]) sage: %time G = C.digraph() CPU times: user 0.39 s, sys: 0.01 s, total: 0.40 s Wall time: 0.39 s
So currently I'm seeing small performance gains, the bigger ones are likely going to come from #14686.

Hi Travis,
The two tests (with and without patch) do not seem to be the same!

@Anne There was some omissions.
New version which fixes the pickling issues and should pass all doctests. #14143 does fix some of the doctests.

Hi Travis,
The patch looks good (I put a reviewed patch on the sage-combinat queue). I am not so happy about the huge doc tests for setstate. As we discussed, perhaps just put a loads/dumps test?
Best,
Anne

I get a warning when building the doc:
[combinat ] docstring of sage.combinat.crystals.letters.CrystalOfLetters:21: WARNING: duplicate citation KN94, other instance in /Applications/sage/devel/sage/doc/en/reference/combinat/sage/combinat/crystals/infinity_crystals.rst

Fixed. Thanks for catching that Jeff (I wish duplicate references would always show up every time you rebuild the doc instead of just the first time).

Anne, could you do a double-check to make sure everything is consistent and works for you? Thanks.

I still get the above mentioned errors:

Did you post an updated patch? I cannot see any mention of affine_permutation in your patch.
