Detailed Description

Generic representation for an optimization method.

This class is a base for a hierarchy of optimizers. It is not intended to be instantiated.

Definition at line 38 of file itkOptimizer.h.

Member Typedef Documentation

◆ ConstPointer

Definition at line 47 of file itkOptimizer.h.

◆ ParametersType

Parameters type. It defines a position in the optimization search space.

Definition at line 57 of file itkOptimizer.h.

◆ Pointer

Definition at line 46 of file itkOptimizer.h.

◆ ScalesType

Scale type. This array defines scale to be applied to parameters before being evaluated in the cost function. This allows to map to a more convenient space. In particular this is used to normalize parameter spaces in which some parameters have a different dynamic range.

◆ Self

Standard class type aliases.

Member Function Documentation

◆ GetCurrentPosition()

virtual const ParametersType& itk::Optimizer::GetCurrentPosition ( ) const

Get current position of the optimization.

◆ GetInitialPosition()

virtual const ParametersType& itk::Optimizer::GetInitialPosition ( ) const

Get the position to initialize the optimization.

◆ GetInverseScales()

virtual const ScalesType& itk::Optimizer::GetInverseScales ( ) const

Get current parameters scaling.

◆ GetNameOfClass()

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

◆ GetScales()

virtual const ScalesType& itk::Optimizer::GetScales ( ) const

Get current parameters scaling.

◆ GetStopConditionDescription()

virtual const std::string itk::Optimizer::GetStopConditionDescription ( ) const

◆ New()

static Pointer itk::Optimizer::New ( )

Method for creation through the object factory.

◆ PrintSelf()

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

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.

Reimplemented in itk::SPSAOptimizer, itk::ParticleSwarmOptimizerBase, itk::PowellOptimizer, itk::RegularStepGradientDescentBaseOptimizer, itk::SingleValuedNonLinearVnlOptimizer, itk::ParticleSwarmOptimizer, and itk::SingleValuedNonLinearOptimizer.

◆ SetCurrentPosition()

virtual void itk::Optimizer::SetCurrentPosition ( const ParametersType param)

Set the current position.

◆ SetInitialPosition()

virtual void itk::Optimizer::SetInitialPosition ( const ParametersType param)

Set the position to initialize the optimization.

◆ SetScales()

void itk::Optimizer::SetScales ( const ScalesType scales)

Set current parameters scaling.

◆ StartOptimization()
