net.sf.cpsolver.exam.criteria.ExamCriterion
net.sf.cpsolver.exam.criteria.additional.DistanceToStronglyPreferredRoom
public class DistanceToStronglyPreferredRoom
Experimental criterion measuring average distance (in meters) to the
strongly preferred room (or rooms) of the examination. The idea is to
prefer rooms that are close to the strongly preference room (if there is
a strongly preferred room but it is not available).
A weight of the average distance between the assigned room(s) and the
strongly preferred room or rooms can be set using
Exams.DistanceToStronglyPreferredRoomWeight property.
To enable this criterion add this class name to Exams.AdditionalCriteria
parameter. For instance:
Exams.AdditionalCriteria=net.sf.cpsolver.exam.criteria.additional.DistanceToStronglyPreferredRoom
