how to implement hard constraint

[ggrrll]

hi,

I just discovered and started testing your tool (running on linux mint, e.g. with runQuickstarts.sh )

• the constraint I need to implement is the fixed N of weekly hours per subject, per classroom -- how should I proceed?

• also: I do not understand why only 1 room and only few time slots are filled? do I have to create as many 'lesson' block as time-slots? (related to 1st)

thanks

should I rather ask on https://groups.google.com/g/optaplanner-dev ?
