getStepSizeGrowthExponent()

double operations_research.pdlp.Solvers.AdaptiveLinesearchParamsOrBuilder.getStepSizeGrowthExponent

(

)

The step size growth exponent defines a step size given by (1 +
(total_steps_attempted + 1)^(-step_size_growth_exponent)) * step_size_.
This should be between 0.1 and 1.

optional double step_size_growth_exponent = 2 [default = 0.6];

Returns

The stepSizeGrowthExponent.

Implemented in operations_research.pdlp.Solvers.AdaptiveLinesearchParams, and operations_research.pdlp.Solvers.AdaptiveLinesearchParams.Builder.

getStepSizeReductionExponent()

double operations_research.pdlp.Solvers.AdaptiveLinesearchParamsOrBuilder.getStepSizeReductionExponent

(

)

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

The stepSizeReductionExponent.

Implemented in operations_research.pdlp.Solvers.AdaptiveLinesearchParams, and operations_research.pdlp.Solvers.AdaptiveLinesearchParams.Builder.

hasStepSizeGrowthExponent()

boolean operations_research.pdlp.Solvers.AdaptiveLinesearchParamsOrBuilder.hasStepSizeGrowthExponent

(

)

The step size growth exponent defines a step size given by (1 +
(total_steps_attempted + 1)^(-step_size_growth_exponent)) * step_size_.
This should be between 0.1 and 1.

optional double step_size_growth_exponent = 2 [default = 0.6];

Returns

Whether the stepSizeGrowthExponent field is set.

Implemented in operations_research.pdlp.Solvers.AdaptiveLinesearchParams, and operations_research.pdlp.Solvers.AdaptiveLinesearchParams.Builder.
