Also, see the Snapshots topic: https://lalescu.ro/liviu/fet/forum/index.php?topic=5840.msg32281;topicseen#msg32281

Please let me know as soon as possible if everything is OK. Please test.

Most welcomed.
The constraint is working perfectly. Timetables generated after adding it are the best i have ever seen.
Thanks so much for the effort to assist

The constraint worked perfectly. The generated timetables for teachers are the best i have ever seen or worked on.Thanks so much for the support.This is just a mile stone in making fet outstanding

[Liviu Lalescu]

Great!

I am ready to release, the only thing remaining is the new fields translations. I am waiting for an answer from my collaborators who translated completely until now (Arabic, Greek, French, and Brazilian Portuguese) (Romanian is done). I hope to release in 1-2 days, but it might take more.

[Cyrus Ireri]

Thats great.As for me,lemmie enjoy what you shared.Its just amazing

[Liviu Lalescu]

I added a new snapshot, in the same usual location, with the initialization of the adding of the constraints a bit improved, and you can now add the interval (h, h+1) (which was forbidden previously, you needed to add at least (h, h+2)).

Please test a bit: add a new constraint in your initial file and maybe generate a bit.

[Cyrus Ireri]

What might be the issue?

[Liviu Lalescu]

Hmm... this is not good!

Please send me your .fet file and, if you have, a starting random seed which produces such a crash. I will investigate in 1-2 hours, now I need to get out for a walk.

[Cyrus Ireri]

 I realized its as a results of conflict of constraints i.e the one you added and teachers max hours continuosly.I needed to select time range well so that they constraints don't crush

[Liviu Lalescu]

No. It is a bug of mine, and I thank you very much for reporting it! I fixed it and released a new snapshot, in the same usual location. Please use this from now on.

I hope to release tomorrow the final version.

[Cyrus Ireri]

Thats great

Hello, how are you? First of all, I'd like to say that I really like the program and it helps me a lot! This condition that was added was exactly what I needed, but I would like to know if it's also possible to limit the day of the week. For example: Limiting the maximum hours on a Wednesday afternoon. Looking forward to your reply.

[Liviu Lalescu]

Hello,

I am fine, thanks! Thank you for the appreciation!

You will need to add for each teacher/students set a constraint activities occupy max time slots from selection: all the activities of that teacher/students set, select with X (red) Wednesday afternoon, max occupied = how many you allow.

I consider that a new more specialized constraint is not needed, but if you really want I can add your suggestion in the TODO.

[Marinho Medeiros]

I think I will need it. The idea of what I need to do will be as follows, in case I haven't been clear: all teachers can take a maximum of 4 time slots every afternoon. But on a specific afternoon, which would be Wednesday, they have a limit on the number of slots they can teach. Teacher A can only teach in 2 time slots, teacher B can only teach in 1 time slot, etc. And I want to exactly limit the maximum number of time slots each teacher can take on Wednesday afternoon. Did I manage to be clearer?

[Liviu Lalescu]

Exactly what I said:

Add one general constraint: teachers max hours in interval.

Then add for each teacher a constraint activities occupy max time slots from selection. The activities = all activities of that teacher, selected slots = Wednesday afternoon (selected with X or red), and max allowed =  2 for A, 1 for B, etc.

If you want, you can send your file so I can show you and test.
