Please let me know if everything is OK, so I can release in a few days a new version.

mmm.... I've tried that new features (max hours continuously constraints) BUT there is ONLY one time that the subject don't have any free period between it... Others are ok

I also try to regenerate the time table again and again.... The result is still the same.. ONLY one time that the subjects don't have any free period between it....Others are A OK

What I do is, I set "max hours continuously for all teacher" to 3 and 4 period bcoz my time table only consists of 3 and 4 period for any classes and lab.... Maybe there is something wrong with the code or.... bug... Why I said this? This is because, if FET broke (have conflict) any constraints... FET will tell us right? But mine is not.... Any idea???

TQ

I have to add a check. Say activity A has duration 4. Then you cannot a constraint of type max hours continuously with less than 4 (say 3). Is that OK with you?

Where is this feature in FET???

Please send me your file and obtained timetables and let me know where the problem is.

Try to add a constraint max hours continuously 2, you will get an error that it is impossible. If you have a teacher with an activity length 4, you cannot add constraint max hours continuously for him (or for all teachers) with 3.

I know why you get teacher Najmi with 6 continuous hours: you added constraint max hours continuously with 6 100% and 8 100% (why did you also add the one with 8, it is useless?). You need to add with 4 hours 100%, and you will never get a teacher working for more than 4 hours in a row.

You're right... I'm just confused.... It only need 4 period ONLY.... I think you should change phrase "hours" to "period" so that others don't confused between both of them. hehe

The feature works charmingly.. thanks

If I would change hours to periods, I should change in lots of other places, which is too late. It is nearly impossible. And if I say periods, others might not understand.

ok hehe

I got another excellent suggestion about gap... Before this, u make "teachers time constraint --> max hours continously for a/all teacher". This feature make sure that lecturers have at least one free period between classes...It works great

How about, u make some features on "student time constraint --> max hours continously for a/all student". This features, same as above, make sure that the student have at least one free period between classes...

What do u think? Is it possible??

TQ

Liviu Lalescu · April 05, 2008, 06:43:21 AM

OK, I'll do that today.

Is such a constraint needed?

Liviu Lalescu · April 05, 2008, 12:34:41 PM

I have made this, please get the latest (see News, or lalescu.ro/liviu/fet/download/test/).

Please tell me if everything is OK. I intend to release tonight, because I found a crashing bug. Please let me know asap if there are any other problems you noticed, because I would like to fix every one of them.
