Parameters used for the sixty "harder" instances.
Note - in all cases of this problem there are 45 timeslots (comprising five days of nine slots). A "1" for the "perfect" field specifies the fact that our instance generator produced a perfect solution (with regards to hard and soft constraints) with the instance. A "0" on the other hand means that the generator produced only a feasible solution with the instance. However, this does not mean there isn't perfect solution for the instance, only that we haven't found it yet!
