Hello again, Victor,

I just saw your old file. Hmm... indeed, you need more gaps.

Please tell me: is this constraint really useful for you and maybe for other Brazilian institutions? If so, I could add new constraints: teacher(s)/students (set) min gaps between activity tag / ordered pair of activity tags per real day.

I could start working right now, please let me know.


Hi Liviu.

It May be useful for other Brazilian institutions in Mornings and afternoons mode!

If you make it I can use the new version.

Liviu Lalescu

Thank you for letting me know, Victor!

I will add new constraints in the official FET, the future version 6.19.0. The constraints will be: teacher(s)/students (set) min gaps between activity tag/ordered pair of activity tags per real day. So, overall, 8 new constraints. Do you have better suggestions for the names/functionality of these new constraints?

I will begin work now or a bit later today. I will let you know when ready. I hope in maximum 2 days we will have a working snapshot for you to test. But I think that the official release will need to wait for Qt-6.7.0 (announced on 26 March 2024).


Thank you, I appreciate it.

I believe it's a good name for these constraints.

Agreed, Thank you for letting me know, Liviu!

I did the most difficult part, the important part of the engine. Tomorrow evening it might be ready. I will let you know, and I hope you will help me with testing, the sooner the better.

Dear Victor,

It is done. See the Snapshots section here on the forum, or:

Please test and let me know.



Dear Liviu.

It works well.

let me know if you need anything else.

Liviu Lalescu

Thank you for the report, dear Victor! Nothing else is needed.

I hope you will like the many improvements added in the interface since your version (you can read the News / ChangeLog). And you will always benefit from the latest version.


Some really cool stuff came in that will work for some teachers, I appreciate all the support, Liviu. ;D

Liviu Lalescu

You are welcome, Victor!

Could you please remind me / explain to me more detailed, for your file, you needed teacher(s) min gaps between building changes per real day and you used the trick with tags? Or the constraints for tags ensure more than this?

I am interested if maybe other teachers/you would need rather teacher(s) min gaps between building changes per real day constraint(s).

You definitely used this interesting trick, and I am not exactly sure I understand it. I would like to understand it completely.

PS: I saw some constraints with min gaps = 0. These are useless.


Hi, Liviu.

Many schools have high school and college preparatory courses in the same building with a few minutes difference in Brazil, so the min gaps between buildings do not solve these issue.

Thank you for informing me, Victor!
