    • Method Detail

      • validateConfiguration

        public boolean validateConfiguration()
        Checks the configuration object for correctness. Should be called before accessing any of the data of the configuration object
        Returns:
        true - The configuration is correct false - The configuration is incomplete or wrong

      • setMinimumIterationsToSurvive

        public void setMinimumIterationsToSurvive​(int minimumIterationsToSurvive)
                                   throws InvalidConfigException
        Set the minimum number of iterations the individuals have to survive.
        Parameters:
        minimumIterationsToSurvive - the minimum number of iterations the individuals have to survive. Number must be greater than 1
        Throws:
        InvalidConfigException - if the supplied parameter do not conform to the required conditions.

      • getMinimumIterationsToSurvive

        public int getMinimumIterationsToSurvive()
        Get the minimum number of iterations the individuals have to survive.
        Returns:
        the minimum number of iterations the individuals have to survive. Is guaranteed to be at least 2.

      • setMinimumSurvivors

        public void setMinimumSurvivors​(int minimumSurvivors)
                         throws InvalidConfigException
        Set the minimum number of individuals to survive.
        Parameters:
        minimumSurvivors - the minimum number of individuals to survive. Parameter must be >= 1
        Throws:
        InvalidConfigException - if the supplied parameter do not conform to the required conditions.

      • getMinimumSurvivors

        public int getMinimumSurvivors()
        Get the minimum number of individuals to survive.
        Returns:
        the minimum number of individuals to survive. Number is guaranteed to be >= 1.

      • setMinimumSurvivorsInPercentage

        public void setMinimumSurvivorsInPercentage​(double minimumSurvivorsInPercentage)
                                     throws InvalidConfigException
        Set the minimum percentage number of individuals to survive.
        Parameters:
        minimumSurvivors - the minimum percentage number of individuals to survive. The parameter is a percentage value and is exacted to be in the interval [0, 1].
        Throws:
        InvalidConfigException - if the supplied parameter do not conform to the required conditions.

      • getMinimumSurvivorsInPercentage

        public double getMinimumSurvivorsInPercentage()
        Get the minimum percentage number of individuals to survive.
        Returns:
        the minimum number of individuals to survive. Number is guaranteed to be in the interval [0, 1].

      • setEvaluationMode

        public void setEvaluationMode​(ParetoOptimalSetStabilityConfig.EvaluationMode mode)
                       throws InvalidConfigException
        Set the evaluation mode that this criterion supports. If mode is set to EXACT_NUMBER, then the criterion searches every time for exactly x candidates who have survived for n iterations. If PERCENTAGE is set as evaluation mode, then the number of the survived candidates is relative to the current amount of candidates in the archive. The NOT_SET value will cause a validation error of the criterion configuration object and an InvalidConfigException if this value is supplied to the set Method of the Configuration class. This value only exists as indicator that the value has not been set.
        Parameters:
        mode - EXACT_NUMBER, then the criterion searches every time for exactly x candidates who have survived for n iterations. PERCENTAGE, then the number of the survived candidates is relative to the current amount of candidates in the archive NOT_SET, will result in a InvalidConfigException.
        Throws:
        InvalidConfigException - if the supplied parameter do not conform to the required conditions.
