  • Method Details

    • getImprovementRateCoefficient

      double getImprovementRateCoefficient()
       Parameter that regulates exchange rate between objective improvement and
 number of neighbors spent. The smaller the value, the sooner the limit
 stops the search. Must be positive.
      double improvement_rate_coefficient = 38;
      Returns:
      The improvementRateCoefficient.

    • getImprovementRateSolutionsDistance

      int getImprovementRateSolutionsDistance()
       Parameter that specifies the distance between improvements taken into
 consideration for calculating the improvement rate.
 Example: For 5 objective improvements = (10, 8, 6, 4, 2), and the
 solutions_distance parameter of 2, then the improvement_rate will be
 computed for (10, 6), (8, 4), and (6, 2).
      int32 improvement_rate_solutions_distance = 39;
      Returns:
      The improvementRateSolutionsDistance.
