When I solved the model in ODM and have requirements saying "The value 1 does not respect the limit 1".
The variable in this constraint is binary variable.
Would you please explain what does it mean?
(I ran the same model in the OPL, and it didn't say that it is infeasible on this constaint. I have other infeasibilities at other constraints which is shown in ODM as well thought.)
thanks a lot.
