      public class ImportantStudentHardConflict
      extends ImportantStudentConflict

  Important student hard conflicts. Same as `ImportantStudentConflict`, but only hard student conflicts are counted (between classes that do not have alternatives, see `Lecture.isSingleSection()`). Weighted by Comparator.ImportantHardStudentConflictWeight parameter. .
