net.sf.cpsolver.exam.criteria.ExamCriterion
net.sf.cpsolver.exam.criteria.RoomPenalty
public class RoomPenalty
Room penalty (penalty for using given rooms). I.e., sum of
ExamRoomPlacement.getPenalty(ExamPeriod)
of assigned rooms.
A weight for room penalty can be set by problem property
Exams.RoomPreferenceWeight, or in the input xml file, property
roomWeight).
