    In the example sub-tour elimination constraints are implemented in a callback. You can use the same idea and even parts of the example code to implement constraint (4). Please note that usually implementing all sub-tour elimination constraints is not practicable due to their exponential amount. Thus, you should also consider adding them as lazy constraints in an analogous way to the example.

    Best regards,
