FET stopped working

[llbuenoo]

Hi,

I am setting up a timetable using FET 5.19 and today I encountered a strange behavior.

After a successful generation I changed the CSS level of the generated HTML and FET stopped working. It start but can't continue after allocate 6 out of 396 activities. The process used to last a few seconds to finish, but now it lasts for more than a minute and can't go further than 6 activities.

I attached the file, if someone can can help.

Thank you.

I am sure you changed some data in between because changing the CSS level does not affect the generation. As FET reports if you stop the generation, check activity with id 20, maybe there is the error.

It is impossible, because you add an constraint to teacher Leandro. he must teach at least 12 hours per day. that is impossible.
Please delete that constraint and your dataset is solvable in just around a second.

Thank you, all.

It was very strange, I removed the restrictions of "min hours daily for a teacher" and it still go stuck, but then I add a restriction of min hours for all teachers with a value of 2 and removed it after a non completion and now it worked.

I still don't got what messed the data in my machine, but now it's back on.

Thank you, guys.
