Periodic weeks (A, B, ... week)

[vg]

Hey,

some months ago I asked the same question already in the German support forum. I got an answer but I think it's not perfect and the exact thing I search. Here's the state of affairs:

- my FET week has 10 (5 * 2) days (Mo A, Tu A, Mo B,...)
- I have two activity tags (A week, B week)
- I create every lesson twice with the same data execpt the tags (because A, B week)
- I block the "A week" tag for B week days and "B week" tag for A week days
- fortnightly activities aren't tagged for A or B, FET "decides" which week

When I generate a timetable the result is quite nice but there are two big problems:
- "TWO" TIMETABLES: the result contains complete different timetables for both weeks, if only one activity is fortnightly it's a big expenditure (the input) and the result is difficult to learn
- SEMANTIC: FET doesn't know about the "split" week. So, e.g. a teacher only want's to have 4 days per week I only can set 8 days per FET week. In worst case FET places the to free days in the B week for example.

How can I solve these problems? (not complete different timetables, not so much to input and constraints for real weeks)

PS: sorry that I created this post in plain text

For the first big problem, please see http://lalescu.ro/liviu/fet/forum/index.php?topic=351 (completely, including reply number #10).

For the second big problem, you need to devise tricks. For max days per week 1, you can add an activity with preferred time week 1, duration = number of hours per day. And for other problems you may need to think of other tricks, maybe by using the important constraint activities occupy max different slots from selection.
