public class DOVSFitness extends SimpleFitness
DOVSFitness is a subclass of Fitness which implements contains important statistics about simulation results of the individual. These statistics will be used to determine the total simulation number that are necessary for a individual. And we hope after such number of simulations are done, we have high confidence of the fitness value of the individual.

    • setup

      public void setup(EvolutionState state, Parameter base)
      Description copied from interface: Prototype
      Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.

      For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.

    • reset

      public void reset()
      Reset the fitness to initial status.

    • numOfObservations

      public int numOfObservations()
      Return the number of simulation have done with current individual.

    • recordObservation

      public double recordObservation(EvolutionState state, double result)
      Record the result of the new simulation. This will update some of the statistics of the current fitness value.
