Hello, Mr. Lalescu.

Thank you very much for your ingenious ideas.
It got me high hopes that might work.
We had already started testing it.

My best wishes!

Hello everyone, hope you all are doing well.

I have this case where local labor laws enforce the school to not schedule classes for a teacher that span throughout 3 periods of the day.

I mean, if a teacher lectures a single class in the morning and a single class in the afternoon, she/he can not lecture any other class at the night period (At least not at the same school. One can decide, at you own free will, to teach on other schools).

I hope the diagram I attached helps to understand this situation.

My question is: how can we enforce these allowed cases to happen on fet programming?

My best wishes for you all.

General Stuff / Re: Recommended CPU for timetabling

"Kind" of an old machine here, Dell Vostro 3500 laptop from 2011 (still running like a charm for daily basic tasks - my favorite machine for meetings and field works):

1min55s on 1st run - https://photos.app.goo.gl/xRvjf3gbBYWuKVbYA
1min53s on 2nd run - https://photos.app.goo.gl/2UbH9U6SSjLMsnAB6
1min52s on 3rd run - https://photos.app.goo.gl/8Wy4HtYaMzohh25X6

Intel i5 M 460 (dual core, 4 threaded) @ 2.528 GHz, locally compiled fet-5.14.3 with Debian GNU/Linux 10 (buster) x86_64, kernel 4.19.0-12-amd64, ran on qt4-default/stable,now 4:4.8.7+dfsg-18+deb10u1 amd64 [installed] Qt 4 development defaults package.

As the cache memory seems to matter for the results, this cpu values are:
L1d cache: 32K, L1i cache: 32K, L2 cache: 256K, L3 cache: 3072K (as seen on lscpu bash command).

I'll try to run the test on other machines (higher and lower specs than this), specially the main desktop I use daily.
