Properties

static pb::MessageParser< MalitskyPockParams > Parser [get]
static pbr::MessageDescriptor Descriptor [get]
double StepSizeDownscalingFactor [get, set]
 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).
bool HasStepSizeDownscalingFactor [get]
 Gets whether the "step_size_downscaling_factor" field is set.
double LinesearchContractionFactor [get, set]
 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).
bool HasLinesearchContractionFactor [get]
 Gets whether the "linesearch_contraction_factor" field is set.
double StepSizeInterpolation [get, set]
 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).
bool HasStepSizeInterpolation [get]
 Gets whether the "step_size_interpolation" field is set.
