GEPRO

Netherlands GEPRO

Netherlands GEPRO was provided by Frederik Geertsema. It represents a large school secondary school in Amsterdam. GEPRO is the name is a small company selling school timetabling software. This dataset was converted from this system, and the constraints were added by hand. It was converted to XHSTT by Gerhard Post.

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 he will attend.

A summary of the data can be found in the following table:
