org.cpsolver.studentsct.weights

## Class EqualStudentWeights

- java.lang.Object
- - org.cpsolver.studentsct.weights.PriorityStudentWeights
  - - org.cpsolver.studentsct.weights.EqualStudentWeights

- All Implemented Interfaces:
    SolutionComparator<Request,Enrollment>, StudentWeights

      public class EqualStudentWeights
      extends PriorityStudentWeights

  Student weight is spread equally among student's course requests. Only alternatives have lower weight. The rest is inherited from `PriorityStudentWeights`.

  - ### Method Detail

    - #### getWeight

          public double getWeight(Request request)

      Overrides:
        `getWeight` in class `PriorityStudentWeights`

    - #### isBetterThanBestSolution

          public boolean isBetterThanBestSolution(Solution<Request,Enrollment> currentSolution)

      Description copied from interface: `SolutionComparator`
      Compares two solutions. Returns true if the given solution is better than its best ever found solution (see `Solution.saveBest()` and `Solution.restoreBest()`).
      Specified by:
        `isBetterThanBestSolution` in interface `SolutionComparator<Request,Enrollment>`
      Overrides:
        `isBetterThanBestSolution` in class `PriorityStudentWeights`
      Parameters:
        `currentSolution` - given solution
      Returns:
        true if the given solution is better than the best ever found solution

    - #### isFreeTimeAllowOverlaps

          public boolean isFreeTimeAllowOverlaps()

      Description copied from interface: `StudentWeights`
      Return true if free time requests allow overlaps
      Specified by:
        `isFreeTimeAllowOverlaps` in interface `StudentWeights`
      Overrides:
        `isFreeTimeAllowOverlaps` in class `PriorityStudentWeights`
      Returns:
        true if free time overlaps are allowed, but the overlapping time is minimized

    - #### main

          public static void main(String[] args)

      Test case -- run to see the weights for a few courses
      Parameters:
        `args` - program arguments
