net.sf.cpsolver.exam.criteria.ExamCriterion
net.sf.cpsolver.exam.criteria.StudentBackToBackConflicts
public class StudentBackToBackConflicts
Number of back-to-back student conflicts. I.e., number of cases when
an exam is attended by a student that attends some other exam at
the previous ExamPeriod.prev() or following
ExamPeriod.next() period. If
isDayBreakBackToBack() is false, back-to-back conflicts
are only considered between consecutive periods that are of the same day.
Back-to-back student conflict weight can be set by problem property
Exams.BackToBackConflictWeight, or in the input xml file,
property backToBackConflictWeight.
