    • generalizedSpread

      public double generalizedSpread(double[][] front, double[][] referenceFront)
      Calculates the generalized spread metric. Given the pareto front, the true pareto front as double [] and the number of objectives, the method return the value for the metric.
      Parameters:
      front - The front.
      referenceFront - The reference pareto front.
      Returns:
      the value of the generalized spread metric
