Hello fet lovers,
Can we add a fictif activity for a teacher but it must not be placed in timetable that will create a gap maybe (empty hours).
Thank you

Hello, Mr. fartoto_dz2004,

Your suggestion was proposed also by other users in the past. Also, with recent versions of FET you can activate/deactivate more constraints with a single click, from the all time/space constraints dialogs (you can filter those which you want and activate/deactivate all of them).

Anyway, I will add your words in the TODO.

Yes i use filter every time but cant we delete filtred rows with a signle click ?
Thank you

Hello Mr Liviu, can you add multiple selection on constraints lists when deleting (mean deleting multiple constaints)
Thank you.

I bet you didn't set the same seed both times if you measure the time, don't you?
Please repeat your test, but don't forget to start generating always with the same seed (see FET -> Settings -> Advanced -> Seed)

By default the seed is always different.

I recorded a few videos about speed on YouTube. Maybe watch one of them.
Maybe this one:

I might do more vidoes about this topic if you want.

Only if you use Qt5 vs Qt6, then FET Qt5 is slower.
Or if you use FET 32bit vs FET 64bit, then FET 32bit is slower.

Or in very rare cases it might be also slower, but Liviu always wrote it in the changelog and news section in that case. A few versions are sadly slower then older ones, because we added so many new features and constraints.

Yes the latest version is slower than older versions, Thanks for your explanations.

I noticed that production in the latest version is much slower than in previous versions.
For example, the same file on the same pc with ver 695 took about an hour, while with version 662 it took less than half an hour.

You need to choose "Excluisive "Morocco"" if you add a teacher.

Thank's Mr Volker but it's not realy usefull cause i want a breakable constraint
Thank you again.

I do not like it because it occupies space and because it is not a good indicator, because you can have the correct count but the incorrect selections.

Thank you! To you, too!

To solve that you can add a counter on each day and the total on left
😁 But it occupies a lot of space

is there any way in M-A mode to ensure that the teacher work only one period mean work in morning or in afternoon ?

the 2 theachers have the same number of hours?

Partially for ex the first has 20 and the second has 19 or 21

Hello, Mr. fartoto_dz2004,

Unfortunately, this is probably very difficult or impossible to make, but I'll write down your suggestion.

Thanks a lot

The constraint activities occupy max time slots from selection, give good result, you don't need a new constraint.

thank you Youssef i tested it but don't give the suitable result.

Hello Mr.Liviu, thanks for the constraint "min resting hours between morning and afternoon for teacher(s)" in M-A mode but if you can modify the weight to be between 0 and 100 like that the program will test if it can achieve the condition otherwise the program will not give any or less resting hours (mining let the constraint be crashable  )
thank you again.

I hope I am correct (but I am very tired). Please try on a small example.

YOU'RE SO CORRECT!!! thank you Mr Liviu.

Mr. Liviu, let me explain more before i test your trick:
I have a teacher who has two subjects an annual (the number of sessions per week is 3) and a quarterly subject with a single session when I add min activities per day for teachers, i sometimes find timetable with a session of the annual subject and a quarterly subject session which means that the teacher in the second quarter is with one session per day. That's my problem

It is not good to post the same question twice, please. I'll redirect from the previous one to here.

If you need at least 2 activities per day from these groups (this is what I understand): I think you need to edit Subactivities (not Activities), adding a special tag (say AT) to those 4 (sub)activities, and then teacher activity tag min 2 hours daily.

If not, let me know more details.

I apologize i won't post again twice the same thing.
I will test your tricks and reply.
Thanks again
