Comment (by ncohen):
Helloooooooo !!!
To be honest I wondered whether we should really have two functions to
remove constraints. It sounds nice to have such a high-level function to
remove many constraints at once in mip.pyx, this one calling the
remove_constraint methods in the backends, but to have a
remove_constraintS in each backend we once more have to duplicate a LOT of
code (like add_linear_constraintS, add_variableS) that may as well be
implemented once and for all in generic_backend.
Then again it is because we are working on pretty different LP. What do
you think ?
