      • 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.

      • getStepSizeDownscalingFactor

        public double getStepSizeDownscalingFactor()
         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

      • hasLinesearchContractionFactor

        public boolean hasLinesearchContractionFactor()
         Contraction factor used in the linesearch condition of Malitsky and Pock.
 A step size is accepted if primal_weight * primal_stepsize *
 norm(constraint_matrix' * (next_dual - current_dual)) is less
 than linesearch_contraction_factor * norm(next_dual - current_dual).
 The default is the value used in Malitsky and Pock (2016).
        optional double linesearch_contraction_factor = 2 [default = 0.99];
        Specified by:
        hasLinesearchContractionFactor in interface Solvers.MalitskyPockParamsOrBuilder
        Returns:
        Whether the linesearchContractionFactor field is set.

        Returns:
        The linesearchContractionFactor.

      • hasStepSizeInterpolation

        public boolean hasStepSizeInterpolation()
         Malitsky and Pock linesearch rule permits an arbitrary choice of the first
 step size guess within an interval [m, M]. This parameter determines where
 in that interval to pick the step size. In particular, the next stepsize is
 given by m + step_size_interpolation*(M - m). The default is the value used
 in Malitsky and Pock (2016).
        optional double step_size_interpolation = 3 [default = 1];
        Specified by:
        hasStepSizeInterpolation in interface Solvers.MalitskyPockParamsOrBuilder
        Returns:
        Whether the stepSizeInterpolation field is set.
