Class IgnoredCommittedStudentConflict

net.sf.cpsolver.ifs.criteria.AbstractCriterion<Lecture,Placement>

net.sf.cpsolver.coursett.criteria.TimetablingCriterion

net.sf.cpsolver.coursett.criteria.StudentConflict

net.sf.cpsolver.coursett.criteria.additional.IgnoredCommittedStudentConflict

All Implemented Interfaces:

Criterion<Lecture,Placement>, InfoProvider<Lecture>, ModelListener<Lecture,Placement>

public class IgnoredCommittedStudentConflict
extends StudentConflict

Ignored committed student conflicts. This criterion counts committed student conflicts (both overlapping and distance) between classes which are connected by a IgnoredStudentConflict constraint. This criterion was created mostly for debugging as these student conflicts are to be ignored.
