I think that I get the idea...

But then I should put 2. If I put 1 a teacher will finish at 21:20 and start at 9. I I put 2 will start at 10.

Is now my understanding correct?

Thanks!

Thanks Liviu,

where can I find more information about option 2?

There is any place where I can read about it?

Thanks in advanced!

Hi Liviu,

I am not sure if I understand how Min Resting Hours for a Teacher is working.

I will give you my problem:

Classes in the afternoon finish at 21:20.
Classes in the morning starts at 08:00.

A teacher must have minimum 12 hours between finish and start the morning afternoon.

I am not sure about how to configure the Min resting Hours for a Teacher to solve my problem.

Really thanks!

Thanks Liviu for your quick reply!

While waiting for your reply I had read and idea in an old post that you suggested!
To remove students break slots!

Will check if the software were I upload the timetable accept that and will be a great solution!

Thanks again!

Hello,
When trying to create the timetable for my teachers I try that if a teacher has classes in the morning to be free in the afternoon. (also classes in the afternoon and free in the morning).
There is any configuration for the program to respect that automatically?
What I use to do is to think in advanced about that and lock that free morning or afternoon for each teacher.
Really thanks!

I have lectures that are 2 hours. Don't know why but the system doesn't allow to put them one before student's break and one after.
Maybe there is any configuration parameters to be modified to get this option valid?
Thanks in advanced!

Thanks to your "magic"  words I had find the problem.... then I have a solution!!

I have now a timetable!!

Thanks a lot again!

Thanks Liviu for your reply!

A question about the algorithm...

If with these constraints there is no solution means it's impossible?

Or if I remove all of them and then got solution and start to put them slowly, is possible to fine one?

Is like the algorithm has memory and I'm every execution has info from the previous one?

Really thanks for your time!

Well most of the constraints were in order to help the program to find a solution...

Had remove most of them and even worst

Half activities placed (600) in 2 seconds... but nothing more...and when the program arrived to 303 trying to place activied nothing else happened

The last activity where was not able to continue is exactly the same as the fet with all the constraints....

The new file attached...

Here ir the zip file.

Now I am out of home will archive it and post it once arrived.

My problem right now is that it get stuck in activity 915 aprox...

I had wait even 1 hour...

Last year maximum time of get and timetable was 20 min and most of the times was much more less...

I think that I had check everything related with the activity that got stucked but even so didn't find the reason why.

Hi There! Is almost 1 monthts that I am "playing" with FET to get a result on my timetable...

But for the moment no way....

Last year I did it... but this year we had some changes that dont know if it's the reason why I am not getting any result....

I think that this is the last version of file that I am working with...

Could anyone take a look?

My first big doubt is about groups/subgrups etc If I am doing in the way that fet expected or not....

The big point is that my timetable is quite complexe... Almost 80 teachers and more that 1000 activies...

the file is too big for attach... then here is the drive link:

Really thanks.
