Comment (by saliola):
I just found a doctest that passes, but should fail:
{{{
sage: from sage.combinat.knutson_tao_puzzles import BK_pieces
sage: BK_pieces(3)
Nablas : [0\0/0, 1\1/1, 2\2/2, 3\3/3]
Deltas : [0/0\0, 1/1\1, 2/2\2, 3/3\3]
}}}
Whoever added this code and doctest should explain what is going on.
And I included a doctest that fails: we need an example of a puzzle with
BK pieces.
{{{
sage: ps = KnutsonTaoPuzzleSolver("BK", 3)
sage: solns = ps('10212', '12012')
sage: sorted(solns, key=str)
}}}
