مشكل تأخير مادة معينة Le problème a été résolu

Greetings again
Sometimes fet produces a table in which a activitys of some subject is always the last Activitys
Is there a way to overcome this problem

salutations à nouveau
Parfois, fet  produit un tableau dans lequel les Activités d'une matière soit toujours les dernières Activités
Y at-il un moyen de surmonter ce problème

[Liviu Lalescu]

Maybe try with constraints subactivities preferred starting times.

[abdeljalil elghazoui]

This is not what I meant
by coincidence fet sometimes produces a table in which the activities  of some subject is the last Activitys
We want the last hour or alternating with all subject
At the very least not be repeated more than twice

[Liviu Lalescu]

You can use subactivities preferred starting times, so some components of a larger split activity are earlier.

Maybe you can also use constraint activities occupy max time slots from selection. Select all activities with this subject, slots - last slots of the day, and max occupied.

Using the subactivities constraint gave very good practical results at my school.
For example our main subjects are splitted into 4 subactivities.
So i set allowed times only from period 1 to 3 to subactivitiies with component number 1.
Similar for all subactivitiies with component number 2.
And period 1 to 5 to subactivitiies with component number 3.

So in worst case the main subject will be at hour 3,3,5,6. Never 2 times at hour 6.

I will try to understand what you said, even this is difficult

In the attached files, I made this request for activities with ids 1..4. The first approach uses subactivities preferred starting times constraints, the second approach uses activities occupy max time slots from selection. See the last 2 constraints in the first file and the last constraint in the second file.
