                                SimpleRealValuedFunction f)
        Creates a new change operator for the given semantics that uses the specified norm for distance measuring and the given function for optimizing.
        Parameters:
        semantics - the semantics used for change.
        norm - the norm used for distance measurement between probabilistic extensions.
        f - the function that is maximized on the set of probabilistic extensions with minimal distance.
