UniTime 4.7 build 91

Course Timetabling

Online Conflicts

• Online/Offline Room: Added a distribution constraints Online/Offline Room that prevents (or penalizes) a pair of classes which are taught on the same day and one is placed in and online room and the other is not.
• No Student Online Conflicts: Added a global constraint No Student Online Conflicts that prevents a student from having two classes on the same day, one being online and the other not.
  • To be registered by setting General.GlobalConstraints=org.cpsolver.coursett.constraint.NoStudentOnlineConflicts.
• Online classes are identified by a regular expression matching the room name and set in the General.OnlineRoom parameter.
  • It defaults to (?i)ONLINE|
  • Classes without a room are considered online when the parameter matches a blank string.
  • If a class has multiple rooms, all rooms must be online for the class to be considered online.

Batch Student Scheduling

Learning Communities: Reservations Priority

• Added a new LC priority level (as the very first one).
• To be used for courses with LC reservations (by setting solver parameter Load.LCRequestPriority=LC).
• This is to ensure that LC courses are assigned first.

Online Student Scheduling

Email Notifications

• Added ability to provide source-action for user/externally initiated emails.
• When showing advisor recommendations, include Critical column when there is at least one course marked as critical.

Bug Fixes

Examination Timetable: Instructor Timetable

• Fixed a NullPointerException thrown when there is an instructor that is assigned only to an exam (or exams) that is not loaded in the solver.

Instructor Detail: Teaching Preference

• Corrected the teaching preference permission check on the Instructor Detail page.
• This fixes the NumberFormatException when the instructor's teaching preference is Prohibited but the maximal teaching load is set.

Solver Parameters: Visible

• Make sure that a new parameter is created as visible when the Visible toggle is not changed (which returns null).

Class Detail: Parent Class

• Corrected Parent Class link.

Academic Session Import: Curriculum Reservations

• Fix CurriculumReservation.area -> CurriculumReservation.areas when importing session from an older instance of UniTime (before the change of the relation to academic areas from one-to-many to many-to-many).
