I asked myself the question the problem comes from the fact that the time constraints are shredded I mean that they are not grouped by category

that's what I did
I edited the constraints in fet then saved them
and I reopen the file in notepad++ to copy the moodele and the rules into the script (program) that I made to generate the fet file

Now you have wrong teacher in constraints teacher max afternoons per week.

Is this the exact syntax?

<ConstraintTeacherMaxAfternoonsPerWeek>
      <Weight_Percentage>100</Weight_Percentage>
      <Teacher>أسماء بن يوسف</Teacher>
      <Max_Afternoons_Per_Week>4</Max_Afternoons_Per_Week>
      <Active>true</Active>
    </ConstraintTeacherMaxAfternoonsPerWeek>

yes with a program that I made

I deleted them
always the same problem

I deleted these constraints but  the second message reappeared

Good morning
Here are the two messages and the file I talked about

I generated using a program I made and from a smaller file template a very large fet file
a message when opening which indicates that certain constraints are false even though they exist in the model file and a crash when I start the generation
how can I attach the file and a screenshot?

this is a suggestion
in fact I want for example that at most two activities with a specific tag are assigned to a room

is it possible to add Max Tag repetition with nsrt version???

these are n activities A1,A2,A3 ...and An which I want to distribute so that at most two are simultaneous
I'm undecided between two choices
that of using the max simultaneous constraint which according to the instructions can reduce the performance of the generation
and the scond choice is creating n imaginary activities B1,B2.....Bn whose preferred rooms are the imaginary rooms S1 and S2 such that B1 and A1 B2 and A2 .....Bn and An start at the same
my question what is the best choice in your opinion knowing that the number n of activities is quite large

Hi
I work with two weeks week A and week B with weekly activities and others fortnightly
is it possible to add to the constraint a teacher max span per day an exception with tow days (for week A an Week B)??

the only problem with the second approach is the enormous number of constraints to be entered
maybe it will be useful to automate them in a future version

the second idea
we work with a week of duration 2N
the first half is week A and the second half is week B
each weekly activity is doubled in two: one containing tag A and the other tag B with the following constraints:
max day between the N
min days between them N
max different room between them 1
all tag A activities start week A and tag B activities start week B
it represents the most realistic model of the situation

beware if you use the min hours daily constraint for students or teachers, we may have to add imaginary activities containing the student or teacher in question
