Thank you so much for the guidelines!!!
You've helped me soooo much!!!
Now I have realised what the problem is... It was not an easy timetable (I supposed to be) with all these constraints especially with max gaps=2...
But now, I know how to face it up...
I thank you once again for the time you spent for my  case...

Looks likes you are right...(5:00 a.m is not a good time for work :-(
I resend the new version...
I'm sorry...

First of all, thank you for the immediate response.
It's getting much better now but I still have problems generating the timetable (311/335 activities in an hour but I don't think it will be a better score). If I increase the "max gaps per day for all teachers" from 2 to 3 or 4 then the score is 323/335)
Regarding 4 in my previous post, i don't have to worry about rooms (no assignments regarding space).
If you are so kind to take a look at my dataset, I would be very glad.
If there's a problem with the language, please tell me...
thank you in advance...

Hi, i'm not sure if I have given the right constraints and the generating process stops from the beginning
1. I have some teachers with a certain activity (let's say ENG) 10 hours (5*2hour activity) and I want  this activity to start at first period. I have put activity constraint "An activity has a preffered starting time"
2.I have some teachers with the same activity (let's say ENG) 8 hours (4*2hour activity) and I want this activity to start at first period. I have put activity constraint "An activity has a set of preffered starting times"
3.I have some teachers with the same activity (let's say ENG) 7 hours (3*2hour activity+1hour) and I want this activity to start at first period. I have also put activity constraint "An activity has a set of preffered starting times"
May be I'm wrong so far but...
4. The same teacher has also other subjects (such as SPORTS let's say 3 hours, MUSIC 3 hours etc) but in order to help the program generate the timetable with more...freedom, I have assigned activities with 1 hour duration with the same name let's say SUBJECT1. So teacher1 have 10 hours ENG and the rest 10 hours SUBJECT1 -with 10 different 1hour activities-and NOT SPORT 3h, MUSIC 3h etc  (total 20 hours for teacher1 per week)
Am I wrong with this approach. It seems to me an easy timetable but I have no results...
I would appreciate if you help me...
thnx
