A set of activities are not overlapping

[canhathuongnhau]

Hello Mr Liviu,
Can you explain detail for me constraint "A set of activities are not overlapping". I dont know how to use it although i read document. Can you give me an example.
Thanks so much. I'm so very happy when hearing your information as soon as possible.

You add a set of activities. It means that no two activities from this set should overlap (be in the same time slots).

If you still need an example, let me know.

Thanks Mr Liviu! Can you give me an example to help me can see it more.

See the attached file. See the teachers' or students' timetable. Each activity from all the 25 is on a different slot.

Thanks your reply so quickly. Mr Liviu, Can you tell me what the situation that you thought when you create this constraint.

[Liviu Lalescu]

I think some users suggested it. They simply wanted two or more activities not to be overlapping; I cannot explain more.
