Heeeeeeeere it is ! The new construction !
As a result, the MOLS table really took a lifetime to fill. So I turned TD
and OA into cached functions and they give their answer MUCH faster. The
bad side is that it also cached the OA/TD, and this is not necessarily a
good idea. The idea would be to cache ONLY the boolean/integer answers,
but I do not know how right now.
Anyway caching the OA/TD is not as bad as it seems, for it will only build
those who are useful in some construction the users asks. When an OA is
not useful, a existence check is made before building the actual design,
so this is cool !
I asked on #15657 if the guys there knew a way to tune cached_function to
only cache some inputs.
Note that MOLS is not a cached_function, because they output matrix
objects .... Does not matter much anyway, the MOLS constructor does not
contain much.
