      • chooseAdvancement

        public AdvanceType chooseAdvancement​(ParameterSetter init,
                                             AdvanceType lastType,
                                             double runResult)
        Description copied from class: HillClimber
        This performs the hill climbing algorithm. In the best case it will traverse the space by (assuming we've just chosen a new parameter):
        • Explore the local space to find which direction to follow. It first will explore to the right (FORWARD) of the current position, then to the left (BACKWARD).
        • Next it will move whichever direction is best of left, right, and the neither (if we're at a peak). If we're on a peak it will return AdvanceType.SWITCH.

        Because of the implementation, this may result in a single spot being executed multiple times in order. Also, this handles the border cases where it cannot move forwards or backwards (but wishes to) by switching.

      • shouldRevert

        public boolean shouldRevert​(double runResult)
        Description copied from class: HillClimber
        Returns true when the previous run's value was greater than runResult or when we're exploring the local space to figure out which direction to go.
        Specified by:

        runResult - the result of the previous run
        if we should revert to the previous space
