Help on generate timetable for very small number of students and activities

[guozhang2001m]

Hi,

I have one new class made of around 30 students and there are many combination of subjects students have taken, and there are only 82 activities but FET would not generate the timetable. Attached is the fet file. Can any FET expert take a look and point me the right direction to solve this issue?

Hello,

I firstly had to rename your subgroups in my file, because my computer will not show those special characters.

Then, I removed some students groups and obtained a smaller impossible file. Please examine it!

I think it is impossible because you made the exact choices of students and teachers. You might need to give flexibility to the program. Maybe you need to read about the 'Block planning' mode. You have also some examples for this mode. Maybe also you need to all the program to group the students differently. This is unfortunately a bit more complicated, you need to use tricks.

Or you might use the 'Official' mode, but using other kind of organizing the data and allowing the program to choose the exact grouping of students and the teachers for them.

Liviu.
