public class StudentDistanceConflict
extends StudentConflict

Student distance conflicts. This criterion counts student distance conflicts between classes. A distance conflict occurs when two classes that are attended by the same student (or students) are placed back-to-back in rooms that are too far a part. The combinations of classes that share students are maintained by JenrlConstraint. The critical distance is measured by DistanceMetric.getDistanceInMinutes(double, double, double, double) and compared witch class break time TimeLocation.getBreakTime().
