max gaps per afternoon

[bachiri401]

HELLO MR LIVIU  I WISH YOU ARE OK
we would like you to add a new constraint if possible
max gaps per afternoon for a teacher
because gaps in the afternoon are annoying and unacceptable not like the morning
thank you sir

[Liviu Lalescu]

OK, I acknowledged your suggestion.

[bachiri401]

thanks
you are always helpful

[Liviu Lalescu]

bachiri401 says to implement this constraint in his custom version: Teachers max 0 gaps per afternoon. This can be hard-coded in the generation code (much easier for me).

His custom version: Teachers max 1 continuous gaps per real day hard-coded in the generation code.

Thanks mr Liviu i am longing to see it come true

[Liviu Lalescu]

I hope I did it correctly.

Please test intensively with combinations of constraints teacher(s):

- afternoons early max beginnings at second hour
- max gaps per day
- max hours daily
- max hours daily half days
- min hours daily
- min hours daily real days
- min days per week.

[bachiri401]

it works successfully
thanks mr Liviu i know i tired you so much

[Liviu Lalescu]

You're welcome! 

[bachiri401]

This version works successfully however it renders difficult timetables impossible

[bachiri401]

Because it is not possible to make 0 gap per afternoon for all teachers please mr Liviu can add this feature as a new constraint for techer\ teachers

[bachiri401]

I know for sure you can do it you never let us down

[Liviu Lalescu]

Dear bachiri401,

It will take a while, I am also busy on other FET works and very tired.

Could we make so that if for instance the name of the teacher ends with "0GA" or other particular string the teacher will need to have 0 gaps in the afternoon, otherwise no constraint for him?

[bachiri401]

YES WHY NOT
I WILL HERE NEED JUST TO ADD TO THE NAMES OF THE TEACHERS CONCERNED 0GA AT THE END
PLEASE GO AHEAD
THANKS
I NEEDED IT ADDED TO MY VERSION IN WHICH THERE NO CONSECUTIVE GAPS PER REAL DAY

[Liviu Lalescu]

Done, please get it from https://lalescu.ro/liviu/fet/download/custom/algeria42-bachiri401/

[bachiri401]

thanks sir
i will test and tell you the results
