Examples

>>> model = mip.Model()
>>> x1=model.add_var(name="1", var_type=mip.INTEGER, lb=0, ub=5)
>>> x2=model.add_var(name="2", var_type=mip.CONTINUOUS, lb=0, ub=5)

>>> model.objective = - x1 - 2 * x2
>>> constr = model.add_constr(x1 + x2 - 6 <= 0)

>>> ommx_instance = adapter.model_to_instance(model)
