  • Method Details

    • compare

      public int compare(double left, T var)
      Description copied from interface: ComparatorVariable
      It compares the baseline metric to the variable metric.
      Specified by:
      compare in interface ComparatorVariable<T extends IntVar>
      Parameters:
      left - the baseline for comparison.
      var - variable which is compared to baseline.
      Returns:
      1 if metric is larger than variable, 0 if equal, -1 if baseline is smaller.

    • compare

      public int compare(T leftVar, T rightVar)
      Description copied from interface: ComparatorVariable
      It compares the metric of the left variable against the right one.
      Specified by:
      compare in interface ComparatorVariable<T extends IntVar>
      Parameters:
      leftVar - left variable
      rightVar - right variable
      Returns:
      1 if metric for left variable is greater, 0 is they are equal, -1 if smaller.

    • metric

      public double metric(T var)
      Description copied from interface: ComparatorVariable
      It returns the metric of the variable given according to the comparator.
      Specified by:
      metric in interface ComparatorVariable<T extends IntVar>
      Parameters:
      var - variable for which metric is computed.
      Returns:
      the metric of the variable according to the comparator.
