  • Method Details

    • hasStepSizeDownscalingFactor

      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];
      Returns:
      Whether the stepSizeDownscalingFactor field is set.

    • getStepSizeDownscalingFactor

      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
 Malitsky and Pock (2016).
      optional double step_size_downscaling_factor = 1 [default = 0.7];
      Returns:
      The stepSizeDownscalingFactor.

    • hasLinesearchContractionFactor

      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];
      Returns:
      Whether the linesearchContractionFactor field is set.

    • getLinesearchContractionFactor

      double getLinesearchContractionFactor()
       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];
      Returns:
      The linesearchContractionFactor.

    • hasStepSizeInterpolation

      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];
      Returns:
      Whether the stepSizeInterpolation field is set.

 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];
      Returns:
      The stepSizeInterpolation.
