net.sf.cpsolver.exam.criteria.ExamCriterion
net.sf.cpsolver.exam.criteria.LargeExamsPenalty
public class LargeExamsPenalty
Front load penalty. I.e., large exam is discouraged to be placed on or after a
certain period.
largeSize: An exam is considered large, if its size is greater or equal to
this number. Value -1 means all exams are small. It can be set by problem
property Exams.LargeSize, or in the input xml file, property largeSize.
largePeriod: Period index (number of periods multiplied by this number) for front load
criteria for large exams. Can be set by problem property
Exams.LargePeriod, or in the input xml file, property largePeriod.
Weight of the front load criterion, i.e., a weight for assigning a large exam
after large period can be set by problem property Exams.LargeWeight, or
in the input xml file, property largeWeight.
