Netherlands GEPRO was provided by Frederik Geertsema.
It represents a large school secondary school in Amsterdam.
GEPRO was the name is a small company selling school timetabling software, owned by Frederik Geertsema.
This dataset was converted by Gerhard Post from this system. The constraints were added by hand, as these did not exist in GEPRO.
This dataset contains an infeasibility that can not be avoided: the school decide to
schedule two lessons (event "IN (6V_1)_237701" and event "LA (6V_d)_238100",
both in event group "gr_Link13945") for student_817 at the same time.
The student will be given the choice which of these lessons to attend.
