Help needed Liviu

[Liviu Lalescu]

I tried to generate on the attached file (deactivated all 7 constraints teacher interval max days per week, and added all teachers min 2 hours daily). It locks on all 8 threads at 441 placed activities, so most probably you need to deactivate min 2 hours daily for the teacher(s) of activity with ID 695 (No. 442 in the initial order) (it has two teachers).

Edit: it seems ID 695 has a single teacher.

This is the file I am trying on now (all teachers but the one of ID 695 have min 2 hours daily, and deactivated all teachers interval max days per week). I reached 484/490 highest-stage, so it might be possible.

I am sorry, but I could not finish on liviu3.fet file. I need to close my generation for now, because I fear my laptop will overheat. I might try a bit more tomorrow.

But you need to generate on liviu3.fet. If you have 8 cores, I advise you to start two FET instances. On one, generate without a time limit on 4 threads, and on the other one generate with a 10 minutes time limit, 1000 timetables. You might have luck. As I said, I reached 484 placed activities.

Removing one constraint doesn't say how long a guy work on this. If it was such an easy task I wonder why you didn't remove that constraint. Removing a single constraint means: Checking the forum regularly, read the question, download the file, open the file, check what is wrong (reading an unknown data set first), write an answer. ...

By the way: We also code many hours, read many hours, help many hours, translate many hours, .... Pay for current, web server, ... If guys pays only the "exact" price for "their" work I wonder who will pay for all the work we done before already. What do you guess how much work is it if we for example only fix a simple misspelling in FET? So fixing, preparing all different download versions and upload them here and on other locations (like Sourceforge, Windows Store, ...)

Let me see my "income" so far:
20 years of work on FET with in total 30€ donations from other guys (and only one guy that payed me for his request of coding; that single guy paid me ok), but I also pay the mirror web server out of my personal money. With that donated money I can run the sever ~3 month. Huhh... who payed all the other months? Who payed the books that I read? Who payed the money that I donated to Liviu in the last years to support him (I supported him even I contributed myself a lot of stuff to FET myself for everybody, ...)? ... I wonder sometimes how Open Source users think...

I considered all weights with <100% weight, and I made their weight 0%. I had to disable the min 2 hours daily for another teacher (because it locked at 489/490), and I obtained a timetable (attached).

I will now disable min 2 hours daily for that teacher in the file with your original weights, and try a bit more.

[Liviu Lalescu]

I obtained a solution on a better file, attached. But I lowered your weights which were under 100%.

Thank you very much. I fully appreciate it
