Distribution First and last periods between classes equally

[mkhlouf]

Hi every one, please i need your help to Distribution the First and last periods between classes equally.
EX:
first class  A
First Class B
First Class C

all have math and English, for the first generation of the timetable, i found that the first A,B has first classes math but C has not.
class c has 3 times last period English and the other classes has only one.
so how can i distribute the important activities via classes equally.
thank you a lot.

Hello, mkhlouf,

I think you need some constraints subactivities preferred starting times/time slots. Careful, subactivities, not activities. Add for component 1 say first hours, and for component 2 say last hours.

Maybe have a look at this video:

thank you very much.

when i tried it shows an error, there is no such activity for this,,,,,

[Volker Dirr]

Please explain a bit more detailed. maybe also write the exact wording of the error.

i fix it, the error was with my data, thank you for your help.
but till now i cannot solve the issue with distribution main courses like math, physics, chemistry, and not repeating same class like math for section b 3 times to be first class, but other sections has it once.
i am searching for fair distribution for the classes between sections or groups for earlier classes.
thank you

note:
i am using special version from the FET, this version is old version="5.14.5

You could attach your file here or send it to me privately by email.

Why are you using FET old 5.14.5 and do not update to the latest version?
