Comment:
Here are some timings.
With the patch:
{{{
sage: B = InfinityCrystalOfTableaux(['B',3])
sage: S = B.subcrystal(max_depth=4)
sage: %time G = B.digraph(subset=S)
CPU times: user 19.55 s, sys: 0.62 s, total: 20.17 s
Wall time: 21.80 s
sage: C = CrystalOfTableaux(['D',4], shape=[2,1])
sage: %time G = C.digraph()
CPU times: user 0.30 s, sys: 0.06 s, total: 0.36 s
Wall time: 0.45 s
}}}
Before:
{{{
sage: B = InfinityCrystalOfTableaux(['B',3])
sage: S = B.subcrystal(max_depth=4)
sage: %time G = B.digraph(subset=S)
CPU times: user 48.83 s, sys: 1.42 s, total: 50.24 s
Wall time: 58.49 s
sage: C = CrystalOfTableaux(['D',4], shape=[2,1])
sage: %time G = C.digraph()
CPU times: user 0.50 s, sys: 0.05 s, total: 0.54 s
