تبقى صالحة لكل أطوار التعليم من الإبتدائي إلى الجامعي مرورا بالثانوي

Hello!
Finally, Now we can work on FET without having to wear glasses. Thanks for adding this beautiful new feature. 💯

Thank you mister Liviu.

Exactement, merci, Hiba Hadi!

Pas de quoi.

Quand vous verrouiller le fichier il faudrait l'enregistrer avant de quitter FET.

Great!

Or: Teacher(s) don't work in two consecutive real days. Hmm... but either your way (teacher(s) no two consecutive real days) or my way it is not clear. Because the user might understand that the teacher is allowed a real day and the two real days before and after must be both totally free....

Please provide me with your file, for testing (when and if I'll do it). I would need also the solution with the teacher working in two consecutive real days. And if your file is too difficult (hours to solve), send me a modified one to solve in ~20 minutes.

OK, Hiba Hadi, I took notice of your comment!

Thank you 🙂

I confirm this new constraint is needed. 2 real days consecutive are very stressful for the teachers.

Thank you, Benahmed! 

It's the truth . I'm not hiding anything...

I confirm.

Great! Very nice and useful trick! Now I understand perfectly.
So really we don't need these 3 constraints and maybe if it's implemented,  they can makes confusing the users and might introduce a new bugs!?

Thank you Volker so much for this nice explanation, and we sincerely hope convincing many users specially who suggested them.

I believe add a new constraints is the last way,  when it's really necessary, and when they aren't any way to solve problems.

Thanks again 🙂

I totally agree with Volker.  3 constraints of rooms? Can we know theirs utility? In a real example if possible?

I think all 3 can be done by pseudo activities already right now.

To Volker: please, can  you tell us how can we do that with pseudo activities?
I don't see any ways!

Thanks for your help

Sadly that happen with "difficult" timetables. We don't know how to fix that.
I always reduce the number of gaps as last step and my tables become difficult by that. Most times i can't sove them, even not after 4 weeks! But in rare cases (maybe 1:1000) I can solve it in less then 20 minutes. That is why always generate multiple timetables with 20 minutes time limit. (On as many cores as i have). By that i got so far - fingers crossed - always a solution after a few hours, even on this extremly difficult timetables.

إذن تنصحون باستخدام التوليد المتعدد في الجداول الصعبة؟! وبالتالي الجداول تصبح مسألة حظ؟!

So you recommend using multiple generation in difficult tables ?! So, the tables become a matter of luck ?!

شكرا على هذا الملف. لكن أعترف أنه ملف غريب نوعا ما، السرعة تتأثر بالبذور العشوائية؟ لم أكن أعلم هذا!  لكن الفرق كبير جدا في توقيت الانتاج، أحيانا بعض الدقائق فقط، وأحيانا أخرى ساعات؟!  ألا تعتقد أنه ربما هنالك جوانب في البرنامج ينبغي لها أن تتغير؟! إنه مجرد سؤال فقط أثاره هذا الملف العجيب

Thanks for this file. But I admit, it's a rather strange file. Speed is affected by random seed. I didn't know this! But the difference is very big in the timing of production, sometimes only some minutes, and sometimes hours ?!

Liviu: Don't you think that there maybe aspects of the program that should change ?! It is just a question raised by this strange file!?
