Help to finish

[CarlosGRaboso]

Hello,
Thanks to Liviu's advice I have managed to master almost all the necessary aspects to develop the schedules of my center.
Now, with the schedules finished in the absence of a subject from a teacher, I am not able to incorporate it, although for hours it is just what the teacher needs to assign. I've checked the restrictions and can't find the key to finish. Adjunto archivo. (It would be necessary to introduce 8 sessions of LANGUAGE of the Teacher 3ºA in the class of 3ºA).
Thank you very much in advance for the help.

Hello!

Please see my two attached files. k.fet is still impossible, after removing all the students years but 3oA. So there might be a mistake there or the timetable is too constrained.

Also, see liviu3.fet. It is solvable, after deactivating 2 hours of LENGUA in 3oA.

I advise you to generate and stop at the highest stage timetable and see the partial timetable, to check for inconsistencies.

Please let me know.

I'm going through the k.fet file, but I don't understand why they don't give teacher hours. It has 30 weekly sessions, of which the following would remain:

mathematics 3rd A: 7 sessions
mathematics 3ºB: 7 sessions
mathematics 3ºA: 8 sessions
mathematics 3ºB: 8 sessions

That make a total of 30 class sessions

In the liviu3 file, I see that the schedules are generated, but in the 3rd A class there are 2 free sessions that coincide with the 2 sessions that the 3rd A teacher is missing.

[Liviu Lalescu]

Don't worry about liviu3.fet, there are two activities deactivated, that is why it generates.

But see please the attached k11.fet file. It is simplified to the maximum. See the activities list. There are 30 activities with teacher 3oA, so they are not allowed in the same slot, so they occupy all the 30 slots of the week. And we have two additional activities which cannot be placed in none of these 30 slots, because they have overlapping students. It is clearly impossible.

Please let me know.

What are the additional activities that you tell me about? Looking at the 3rd A group I see that they have their 30 sessions and that the 3rd D teacher, too, ... I can't see what activities you mean.

[Liviu Lalescu]

Please see my file k11.fet above.

Hello, Liviu.
First of all, thank you for your prompt response. I answer you now, that I have been the weekend without connection.

In the fet11 file I see all the activities that actually have a duration of 32 sessions. But 30 correspond to the teacher of 3ºA and, the 2 sessions of 3ºA_V 3ºB_V correspond to the teacher of 3ºC, so I still don't see why it is not generated if the Teacher 3ºA has just 30 sessions, which are the sessions available in the week.

Thank you very much and sorry for the inconvenience I am giving you ...

Hello,

Absolutely no problem, but I cannot explain better than this:

"But see please the attached k11.fet file. It is simplified to the maximum. See the activities list. There are 30 activities with teacher 3oA, so they are not allowed in the same slot, so they occupy all the 30 slots of the week.

Volker or other users, could you please see this topic and answer to CarlosGRaboso?

Teacher Maestra 3°A needs 30 slots.
But the activities of teacher Maestra 3°C can't be at the same time as the activities of Maestra 3°A, because he teachs the same students like Maestra 3°A. So you need to least 32 slots.

[CarlosGRaboso]

Solved! Instead of associating 3ºA_R / V with 3ºB_R / V, I have associated 3ºA_R / V with 3ºC_R / V.

Thank you very much for your help!
