Custom FET for Algerian schools

[Liviu Lalescu]

I do not agree that 1 day exception / 2 days exception can be made (so that we unify Algeria and Morocco FET), because for instance in FET-Morocco with 1 day exception the teacher T works 4 real days and in one real day he works both morning and afternoon. So the constraint for min real days per week = 5 is too strong and denies good timetables.

thanks it works perfectly

yes I agree with you, but I think it depends on the number of hours of work per week for each teacher. so the number of days worked per week depends on one teacher to another.

[bachiri401]

we need this constraint because in algeria we have 5 days per week and every teacher must have one day free.
but sometimes some teachers get 2 free days this makes teachers envey one another so we need to make the costraint min days per week 4 so that all the teachers will get equal timetables

[Benahmed Abdelkrim]

for a teacher who has a higher number of hours per week, we can impose min days = 5, for another who has a lower number we can impose min days = 4 or lower.

so the number of days worked per week depends on one teacher to another.

Indeed. But I think I will keep and update Algeria and Morocco. Maybe our Moroccan users can write.

thanks it works perfectly

You are welcome! Thank you for your suggestion, as well!

Please test with more files (also other users, not only you, bachiri401) and after a few or more days I hope I will update Algeria and Morocco. But it is vital it works correctly (so that the files solve, they don't become impossible). Test multiple generation on more files (just let it compute 10 timetables or more, no need to check the results, if the generation is successful it is surely correct).

OK, I understood.

for a teacher who has a higher number of hours per week, we can impose min days = 5, for another who has a lower number we can impose min days = 4 or lower.

so the number of days worked per week depends on one teacher to another.

Indeed. I will let the Moroccan users to tell us as well. But I think it is much better to keep both versions (Algeria and Morocco) for now, as it is also not difficult.

[bachiri401]

sure i 'll do it

[bachiri401]

it worked perfectly i tried it many times
Thanks that's a great deed for us

[Liviu Lalescu]

Thank you for your feed-back!

I hope I will release the new versions of Algeria and Morocco soon, in a few days. I'll announce it.

[Liviu Lalescu]

On 17 October 2018 I released a new version. Suggested by bachiri401 the constraint teacher(s) min days per week considers real days, and also I updated the Arabic translation, by Benahmed Abdelkrim.

It was released the new version, FET-5.27.3-Algeria36.

[bachiri401]

Thanks for everything you are doing for us

[Liviu Lalescu]

You are welcome!

good morning
i hope i am not too demanding
we have two activities A1 and A2
we need (if these two activities come on the same day i.e half day activity 1 must be before activity 2)
because sometimes we have sport then maths we need maths to be before sport

THANK YOU VERY MUCH INDEED

[bachiri401]

 in our school for example:
we have 28 classes each class has a sport activity of 2 hours cosecutive. we have only two staduims. so we must have sport on the two first hours of the morning for at least 8 classes then these classes will have other activities. that's why we need a constraint to make the activities after sport not to be maths or physics.
THANKS

[Liviu Lalescu]

In the official FET, there is a constraint introduced recently:

17 June 2018, FET 5.36.0 released
- Added a new constraint, two activities are ordered if they are on the same day (suggested by math).

Is this what you are suggesting for Algeria and Morocco versions?
