      • hasStepSizeDownscalingFactor

        public boolean hasStepSizeDownscalingFactor()
         At every inner iteration the algorithm can decide to accept the step size
 or to update it to step_size = step_size_downscaling_factor * step_size.
 This parameter should lie between 0 and 1. The default is the value used in
 Malitsky and Pock (2016).
        optional double step_size_downscaling_factor = 1 [default = 0.7];
        Specified by:
        hasStepSizeDownscalingFactor in interface Solvers.MalitskyPockParamsOrBuilder
        Returns:
        Whether the stepSizeDownscalingFactor field is set.
