What do you think about a function that shows for each hour of the day how many teachers can be assigned at every hour (under the constraints set).
In this way it's possible to see what are the most problematic hours
This would be more like a statistic? Let me write this down in the TODO. But I don't think it is a very useful function, as more factors contribute to the difficulty of a timetable.
Let us hear what other users say.
if i see that a particular hour have only 1 or 2 teacher available (or no one) I'm going to review the constraints
Thank you for your work and your attention
