Hi ...

                 I simply click on the button: [A set of activities has same starting time (day + hour)]

at the end of this session ... interchanged the two groups ....

The group_2_ will follow the course Technique immediately after the course Techique  group_1_

AND

The group_1_  will follow the computer course immediately after  the group _2_ ....

         I simply click on the button [Two consecutive activities]

    Why F.E.T blocks?

Please stop the generation after 116 activities were placed and see the highest stage timetable for the students and teachers of 587, 588, 805 and 806. There seems to be something weird about them.

Oh ! yes sir
But ....
I do not know what to do about it

[Liviu Lalescu]

I don't know. Please try to generate, then stop and see the highest stage timetable - see in parallel the timetable for students and teachers. Try to understand why the program blocks.
