      • error

        public double error(double result,
                    double expectedResult)
        Returns the error between the result and the expected result of a single data point.

      • 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.

        Specified by:
        setup in interface Prototype
        Specified by:
        setup in interface Setup
        Overrides:
        setup in class GPProblem

      • evaluate

        public void evaluate(EvolutionState state,
                     Individual ind,
                     int subpopulation,
                     int threadnum)
        Description copied from interface: SimpleProblemForm
        Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
        Specified by:
        evaluate in interface SimpleProblemForm

      • describe

        public void describe(EvolutionState state,
                     Individual ind,
                     int subpopulation,
                     int threadnum,
                     int log)
        Description copied from class: Problem
        Part of SimpleProblemForm. Included here so you don't have to write the default version, which usually does nothing.
        Specified by:
        describe in interface SimpleProblemForm
        Overrides:
        describe in class Problem
