(Does that even make sense mathematically? I'm not familiar with the gale
ryser theorem.) If not, I agree with Nathann.
Not that I know. When I write doctests using LP, I try to find examples
for which the solution is unique, but there are many matrices solving the
gale-ryser proble (ryser's algorithm even lets one enumerate them), and
the solvers have no reason to return one rather than the other. Adding a
fake objective functions to make the answer unique on the same problem
would touch the running time just to make the doctests easier to write,
which clearly isn't a good idea :-D
