## Class Test

- java.lang.Object
- - org.cpsolver.studentsct.online.Test

-     public class Test
      extends Object

  An online student sectioning test. It loads the given problem (passed as the only argument) with no assignments. It sections all students in the given order (given by -Dsort parameter, values shuffle, choice, reverse). Multiple threads can be used to section students in parallel (given by -DnrConcurrent parameter). If parameter -Dsuggestions is set to true, the test also asks for suggestions for each of the assigned class, preferring mid-day times. Over-expected criterion can be defined by the -Doverexp parameter (see the examples bellow). Multi-criteria selection can be enabled by -DStudentWeights.MultiCriteria=true and equal weighting can be set by -DStudentWeights.PriorityWeighting=equal).
  Usage:
  java -Xmx1g -cp studentsct-1.3.jar [parameters] org.cpsolver.studentsct.online.Test data/pu-sect-fal07.xml
  Parameters:
  - -Dsort=shuffle|choice|reverse ... for taking students in random order, more choices first, or more choices last (defaults to shuffle)
  - -DnrConcurrent=N ... for the number of threads (concurrent computations of student schedules, defaults to 10)
  - -Dsuggestions=true|false ... true to use suggestions (to simulate students preferring mid-day, defaults to false)
  - -Doverexp=xover|bxover-xdisb%|xover-xmax|bxover-xmax-xdisb% for over-expected criterion, examples:
    - 1.1 ... `PercentageOverExpected` with OverExpected.Percentage set to 1.1 (xover)
    - b1-10 ... `AvoidUnbalancedWhenNoExpectations` with OverExpected.Percentage set to 1 and General.BalanceUnlimited set to 10/100 (xdisb%)
    - 0.85-5 ... `FractionallyOverExpected` with OverExpected.Percentage set to 0.85 and OverExpected.Maximum set to 5 (xmax)
    - 1.1-5-1 ... `FractionallyUnbalancedWhenNoExpectations` with OverExpected.Percentage set to 1.1, General.BalanceUnlimited set to 5/100, and OverExpected.Maximum set to 1
  - -DStudentWeights.PriorityWeighting=priority|equal ... priority or equal weighting (defaults to priority)
  - -DStudentWeights.MultiCriteria=true|false ... true for multi-criteria (lexicographic ordering), false for a weighted sum (default to true)
  - -DNeighbour.BranchAndBoundTimeout=M ... time limit for each student in milliseconds (CPU time, defaults to 1000)
