Student Sectioning: Priority Request Date Order

  • added a student order comparing students by:
  1. student priority (priority students first)
  2. average course request timestamp (student with eariler requests first)
  3. number of choices (student with fewer choices first)

Revision 8246405 by tomas-muller muller@unitime.org (18-Oct-2021 2:40 PM)

Student Sectioning: Request Priority Report

  • include the first column with student id (__Student)

Revision 2367140 by tomas-muller muller@unitime.org (18-Oct-2021 2:39 PM)

Online Student Scheduling: Reservation Limit Cap

  • do not cap the reservation limit of OnlineReservation any further
  • it is already capped by the config/class limits (XReservation.getLimit() minus the current
    enrollment, except of the student in question)
  • capping the limit any further can create discrepancies as the config/class limits are computed
    differently
    (excluding other students, possibly causing the class no longer available errors in the
    check-assignment action)

Revision 9ad6480 by tomas-muller muller@unitime.org (6-Aug-2021 2:01 PM)

Parallel Solver: Solver Thread

  • set the iStop variable to its previous state at the end, before calling onStop or onFinish

    immediately)

    setting a limit on the number of iterations (2x the initial size of the request queue)

Revision fa515df by tomas-muller muller@unitime.org (23-Mar-2021 6:09 PM)

Student Scheduling Algorithm: backtrack and branch&bound after restore best

  • when priority and/or critical students are preferred, added an ability to cycle through the
    students/requests more than once
    Sectioning.CriticalRounds for critical courses (defaults to 1)
    Sectioning.PriorityRounds for priority students (defaults to 1)
  • when cycling through the priority students, added ability to include all students of the desired
    or higher priority during the last round
    when Sectioning.PriorityLastRoundAllStudents is true (defaults to false)

Revision 9bca75a by tomas-muller muller@unitime.org (7-Jan-2021 3:53 PM)

Student Scheduling: Student Groups & Accommodations

in preparation for being able to start using student minors:

  • created separate lists for student groups and accommodations (instead of storing them as minors
    which have not been used so far)
  • removed the old student academic area - classification and student academic area - major pairs
    (use the student area, classification, major tripplets)
  • updated XML load and save (XML load does understand the old format, creting student groups and
    accommodations)
