Comment(by ncohen):
Oh, but that is not necessarily a problem in this case. I mean, it would
be necessary to hard-code the copy of the whole problem in low-level
functions of the MILP class to make it work anyway, so the operations
would still work by copying the MILP object just before solving it and it
would not change the complexity, would it ?
But if you do that, you definitely know that you are copying the program
and do not believe that you are just "adding a constraint" while what Sage
does is actually much much longer.
