Thanks a lot! I will have a look when i get home.

Ok, I'll see what i can do. Thank you very much!

Second seed, single 355/356 in 7m14s.

Yes, i got it after my last post. Now, first random seed, single, 3min14sec.

So, with your first random seed, 8 threads, managed 354/356 in two threads, both at about 18 minutes.
I'll try the other seed as well.

Ok, thanks. I'll try it .

I don't know how to check the initial order nor the random seed. I'll do some reading :-)
However i checked that the semi-finished timetables (the ones that only the specific activity was not placed) were different.
I'll try the stop and start method.

No, i don't think so, I think I've found the proper constraints. If it keeps failing, I'll have to relax something. The interesting observation I've made is that in this 32 hour effort as well as in previous ones with almost the same constraints, the activity that is always left to be placed is the one with id 573. I've spent some time trying to figure out why it's always the same, but with no results. That can't be a coincidence however, unless there's a certain way that fet tries to generate the timetable, that leads to this.
I'll give it some more thought.

Great machine!
Ok, i attach the file You cannot view this attachment.
Thanks!
(Meanwhile, my wife accidently stopped the generarion at 32 and a half hours... I'll start it over tommorrow.

Hello everyone,
I'm trying to make a timetable and it seems the conditions i've set are quite tight.
I'm running fet on an old i7 proccessor, 3 threads and till now (that's 32 hours) it has managed to place 354, 354 and 355 out of 356 activities at 3, 4 and 10 hours respectivelly.
My question is, how much time should i let it run? Is there a rule about this? What's your experience?

It seems to work fine. Thank you!

That would be nice!

Thanks. Let's hope that it is useful to FaustFet

Ok, thanks!

I'm not sure if i've understand the case but i'll take my chances and make a try for a solution:

What if you made an 8 hours-per-day schedule, made a 1+1+1+1 dummy activity (let' call it "LastHour"), restrict it to take place only during the 8th hour. Then use another restriction so that LastHour and your Excercise activity have minimum 1 day between them.
Does it make any sence?
