      • hasStepSizeReductionExponent

        boolean hasStepSizeReductionExponent()
         The step size reduction exponent defines a step size given by
 (1 - (total_steps_attempted + 1)^(-step_size_reduction_exponent)) *
 step_size_limit where step_size_limit is the maximum allowed step size at
 the current iteration. This should be between 0.1 and 1.
        optional double step_size_reduction_exponent = 1 [default = 0.3];
        Returns:
        Whether the stepSizeReductionExponent field is set.

      • getStepSizeReductionExponent

        double getStepSizeReductionExponent()
         The step size reduction exponent defines a step size given by
