Interface AggregateObjectiveComparator

All Superinterfaces:
Comparator<Solution>, DominanceComparator
All Known Implementing Classes:
AbstractAggregateObjectiveComparator, LinearDominanceComparator, LinearObjectiveComparator, MinMaxDominanceComparator, MinMaxObjectiveComparator, VectorAngleDistanceScalingComparator
public interface AggregateObjectiveComparator extends DominanceComparator, Comparator<Solution>
Compares solutions based on a computed aggregate value from the objective values. This comparator and its implementations are intended for use with single-objective algorithms.

  • Method Details

    • getWeights

      double[] getWeights()
      Returns the weights used by this aggregate function.
      Returns:
      the weights

    • calculate

      double calculate(Solution solution)
      Calculates the aggregate value of the solution using this aggregate function.
      Parameters:
      solution - the solution
      Returns:
      the aggregate value (smaller is better)

    • fromConfiguration

      static AggregateObjectiveComparator fromConfiguration(TypedProperties properties)
      Creates an aggregate objective comparator from the given configuration.
      Parameters:
      properties - the configuration
      Returns:
      the comparator, or null if one is not explicitly configured

    • toConfiguration

      static TypedProperties toConfiguration(AggregateObjectiveComparator comparator)
      Returns the configuration for the given aggregate objective comparator.
      Parameters:
      comparator - the comparator
      Returns:
      the configuration
