FET with five terms / for Finland (Five 7 weeks terms in a school year)

[mikkojoo]

I think I got it.
I had to make 25 days in a week, monday1, tuesday1, ... ... thursday5, friday5.

Exactly, please read the help for the FET terms mode, in the Help menu of FET.

Again making timetables and doing well.

It would be nice to have constrain "Min activities from a set in a term" - I have done it with "a set of activities has a set of preferred timeslots" but it's quite hard to make for each term and each set of activities.

Generally, FET is very smooth to use and handy.

[mikkojoo]

And; it would be useful if would work like this

min activities from a set of activities in a term && in not more than minimum then == 0

Then it would be possible to define number of occupied terms and minimum&maximum of activities in a term >> more or less equal number of activities in occupied term (and others to be 0).

Hello,

I am glad you like it!

OK, I will try to make this, since it seems useful. It might be difficult, but it is useful. Could you send me your input file? I cannot guarantee that it is possible to implement it, though.

Do you know about the existing constraint activities occupy min time slots from selection? It might help (but you need to add n_terms activities).

As for me, I have a personal appeal, for users of FET in Finland: please spread the word about FET, and please spread the word that this project desperately needs financial support, as I am not helped by any organization (only by the kind individual donations).

Here is the zipped file

There are lots of constraints...
There are many things we have to consider; certain activities in one term, others spanned to certain terms, usually we don't want to have "empty"  terms between occupied terms.

[Liviu Lalescu]

Thank you for your file! Could you indicate to me what constraints should be removed and which ones of type min activities in a term should be added, if I make it, so I can test it?

[mikkojoo]

It's hard for me to say what should be removed...

[mikkojoo]

But, for example activities "MA" should all have constraints for each group:
1) min 2 activities in a term
2) no empty terms between occupied terms

Then there should be a constraint "max 3 activities in a term" for each set of activities. This for everything.

[mikkojoo]

For example for "BG" I have done same thing like this:
a) there are 9 activities per group altogether
b) they should be in terms 2,3,4, so
c) constraint "max days between avtivies" = 16
d) constarint "max activities in a term" = 3

[mikkojoo]

But for MA (maths) it's more complicated because
- there are more activities (9 or 12)
- they should be spanned in 4 terms (9 acts) or 5 terms (12 acts)
- there should be a) min 2 acts in a term b) max 3 acts in a term

[mikkojoo]

Do You get my point or is there something I'm missing / should do other way?

I will be off for a while, doing some outdoor sports, because it's finally spring here in Finland 

[Liviu Lalescu]

OK, I got the idea. Please let me know if constraint min activities from a set in a term would be enough; I mean, in this case could you use the other constraints to say that there is no empty term in between occupied terms?

[Liviu Lalescu]

I understood. I will test on some simpler files and then on your file. Please let me know if a new constraint type min activities from a set in a term with/without allowing empty terms would be enough.

Have a nice sport!
