net.sf.cpsolver.exam.criteria.ExamCriterion
net.sf.cpsolver.exam.criteria.PerturbationPenalty
public class PerturbationPenalty
Perturbation penalty. I.e., penalty for using a different examination period than
initial. Only applicable when isMPP()
is true (minimal
perturbation problem).
A weight of perturbations (i.e., a penalty for an
assignment of an exam to a place different from the initial one) can be
set by problem property Exams.PerturbationWeight, or in the input xml
file, property perturbationWeight).
