Custom FET for Algerian schools

[Liviu Lalescu]

By popular request, I upgraded to Algeria42, but I only released a snapshot (test version) for now. I need you to test and after that I will release the Algeria42 version. Also the Arabic translation is not completed, yet. I hope with the help of Benahmed Abdelkrim we will have it.

The new features:

1) Teacher(s) min hours per morning, suggested by fethi_dz.

2) Teacher(s) begin afternoons early, respecting a maximum of n beginnings at second hour, suggested by Sadi 213.

Please test intensively and report the results.

The link, as usual: https://lalescu.ro/liviu/fet/download/custom/algeria/  (get the snapshot for Algeria42 version).

Thanks Mr LIVIU but I think the new constraint (min hours per morning ) added as a new constraint like this is not good
this constraint should be just a part of the old constraint (min hours daily)

Then other parts are needed (min hours per afternoon/max hours per morning and per afternoon)

Thank you, Mr. Bachiri, but:

I thought and this is the best way to add it. Not to confuse other users (I think only a few users will use min hours per morning). There are also other constraints (teacher(s) min mornings/afternoons per week) which need other constraints to be present.

Then other parts are needed (min hours per afternoon/max hours per morning and per afternoon)

For now, it was difficult enough for me. And I assume the other constraints are not used. And they can be added at a later time.

I added a new snapshot, minor things changed. Same link: https://lalescu.ro/liviu/fet/download/custom/algeria/ (get the snapshot Algeria42-21-aug-2019).

sometimes we find a problem in case of 2gaps per real day
we need these two gaps to be sepatated not consecutive
please mr LIVIU could make them not cosecutive

[bachiri401]

because i made max gaps per real day at 2 , THE RESULT WAS ; some teachers got two sepatred gaps while others got them together which is not good

[Liviu Lalescu]

Could you maybe use constraint teacher(s) max hours continuously or the new constraint teacher(s) begin afternoons early max beginnings at second hour?

[bachiri401]

this won't solve the problem because a teacher can start afternoon early but still he stopped at the third hour of the morning

[Liviu Lalescu]

Maybe with teacher(s) max 3 hours consecutive or teacher(s) min 3 hours per morning.

[bachiri401]

Can't you sir port this constraint max consective hours for a teacher to be max consective gaps for a teacher

[Liviu Lalescu]

Other users suggested this (max consecutive gaps for teachers) for FET official, and at that time I told them it was too difficult.

But thinking now, it might be possible teacher(s) max 1 consecutive gaps per real day. Is this what you need? I could prepare some test version for you only, and if it is useful I'll add to the Algeria and Morocco FET.

For the beginning, I will hard-code this in the generating code, for all the teachers. Is that OK for now?

Then, I will need you to test and send me a test file as well. Maybe making it tonight.

[bachiri401]

Yes that's what i need but 0  cosecutive gap per real day i,e each gap must be alone no cosective gaps

[Liviu Lalescu]

Yes that's what i need but 0  cosecutive gap per real day i,e each gap must be alone no cosective gaps

It is 1 consecutive gaps, since it is alone. If you say 0, it is no gap. If you say 2, it is two gaps joined together.

I think I will begin work now. Please prepare a file and send it.

If I cannot succeed or am too tired, I will write and we'll try again tomorrow.
