public class InstructorBackToBackConflicts
extends StudentBackToBackConflicts

Number of back-to-back instructor conflicts. I.e., number of cases when an exam is attended by an instructor that attends some other exam at the previous ExamPeriod.prev() or following ExamPeriod.next() period. If StudentBackToBackConflicts.isDayBreakBackToBack() is false, back-to-back conflicts are only considered between consecutive periods that are of the same day.

Back-to-back instructor conflict weight can be set by problem property Exams.InstructorBackToBackConflictWeight, or in the input xml file, property instructorBackToBackConflictWeight.
