Detailed Description

Limited memory Broyden Fletcher Goldfarb Shannon minimization with simple bounds.

This class is a wrapper for converted Fortran code for performing limited memory Broyden Fletcher Goldfarb Shannon minimization with simple bounds. The algorithm mininizes a nonlinear function f(x) of n variables subject to simple bound constraints of l <= x <= u.

Member Function Documentation

◆ CreateAnother()

virtual::itk::LightObject::Pointer itk::LBFGSBOptimizerv4::CreateAnother ( ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

◆ GetBoundSelection()

virtual const BoundSelectionType& itk::LBFGSBOptimizerv4::GetBoundSelection ( ) const
virtual

◆ GetCostFunctionConvergenceFactor()

virtual double itk::LBFGSBOptimizerv4::GetCostFunctionConvergenceFactor ( ) const
virtual

◆ GetInfinityNormOfProjectedGradient()

virtual const double& itk::LBFGSBOptimizerv4::GetInfinityNormOfProjectedGradient ( ) const
virtual

Get the current infinity norm of the project gradient of the cost function.

◆ GetInitialPosition()

ParametersType& itk::LBFGSBOptimizerv4::GetInitialPosition ( )
inline

Get the position to initialize the optimization.

Definition at line 110 of file itkLBFGSBOptimizerv4.h.

virtual unsigned int itk::LBFGSBOptimizerv4::GetMaximumNumberOfCorrections ( ) const
virtual

◆ GetNameOfClass()

virtual const char* itk::LBFGSBOptimizerv4::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::LBFGSOptimizerBasev4< vnl_lbfgsb >.

virtual const BoundValueType& itk::LBFGSBOptimizerv4::GetUpperBound ( ) const
virtual

◆ New()

static Pointer itk::LBFGSBOptimizerv4::New ( )
static

Method for creation through the object factory.

◆ PrintSelf()

void itk::LBFGSBOptimizerv4::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Object.

◆ SetBoundSelection()

void itk::LBFGSBOptimizerv4::SetBoundSelection ( const BoundSelectionType select)

Set the boundary condition for each variable, where select[i] = 0 if x[i] is unbounded, = 1 if x[i] has only a lower bound, = 2 if x[i] has both lower and upper bounds, and = 3 if x[1] has only an upper bound

◆ SetCostFunctionConvergenceFactor()

virtual void itk::LBFGSBOptimizerv4::SetCostFunctionConvergenceFactor ( double  )
virtual

Set/Get the CostFunctionConvergenceFactor. Algorithm terminates when the reduction in cost function is less than factor * epsmcj where epsmch is the machine precision. Typical values for factor: 1e+12 for low accuracy; 1e+7 for moderate accuracy and 1e+1 for extremely high accuracy.

◆ SetInitialPosition()

void itk::LBFGSBOptimizerv4::SetInitialPosition ( const ParametersType param)

Set the position to initialize the optimization.

◆ SetLowerBound()

void itk::LBFGSBOptimizerv4::SetLowerBound ( const BoundValueType value)

Set the lower bound value for each variable.

◆ SetMaximumNumberOfCorrections()

virtual void itk::LBFGSBOptimizerv4::SetMaximumNumberOfCorrections ( unsigned int  )
virtual

Set/Get the MaximumNumberOfCorrections. Default is 5

◆ SetMetric()

void itk::LBFGSBOptimizerv4::SetMetric ( MetricType metric)
overridevirtual

Plug in a Cost Function into the optimizer

Implements itk::SingleValuedNonLinearVnlOptimizerv4.

◆ SetScales()

void itk::LBFGSBOptimizerv4::SetScales ( const ScalesType )
override

This optimizer does not support scaling of the derivatives.

◆ SetUpperBound()

void itk::LBFGSBOptimizerv4::SetUpperBound ( const BoundValueType value)

Set the upper bound value for each variable.

◆ StartOptimization()

void itk::LBFGSBOptimizerv4::StartOptimization ( bool  doOnlyInitialization = false)
overridevirtual

Start optimization with an initial value.

Reimplemented from itk::ObjectToObjectOptimizerBaseTemplate< double >.
