getGlopParameters()

com.google.ortools.glop.GlopParameters com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptionsOrBuilder.getGlopParameters

(

)

Parameters to control glop's presolver. Only used when use_glop is true.
These are merged with and override PDLP's defaults.

optional .operations_research.glop.GlopParameters glop_parameters = 2;

Returns

The glopParameters.

Implemented in com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptions.Builder, and com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptions.

getUseGlop()

boolean com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptionsOrBuilder.getUseGlop

(

)

If true runs Glop's presolver on the given instance prior to solving.
Note that convergence criteria are still interpreted with respect to the
original problem. Certificates may not be available if presolve detects
infeasibility. Glop's presolver cannot apply to problems with quadratic
objectives or problems with more than 2^31 variables or constraints. It's
often beneficial to enable the presolver, especially on medium-sized
problems. At some larger scales, the presolver can become a serial
bottleneck.

optional bool use_glop = 1;

Returns

The useGlop.

Implemented in com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptions.Builder, and com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptions.

hasGlopParameters()

boolean com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptionsOrBuilder.hasGlopParameters

(

)

Parameters to control glop's presolver. Only used when use_glop is true.
These are merged with and override PDLP's defaults.

optional .operations_research.glop.GlopParameters glop_parameters = 2;

Returns

Whether the glopParameters field is set.

Implemented in com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptions.Builder, and com.google.ortools.pdlp.PrimalDualHybridGradientParams.PresolveOptions.
