#include <itkMultiGradientOptimizerv4.h>
Multiple gradient-based optimizers are combined in order to perform a multi-objective optimization.
This optimizer will do a combined gradient descent optimization using whatever metric/optimizer gradient sub-optimizers are passed to it by the user. The learning rate or scaleestimator for each sub-optimizer controls the relative weight of each metric in the optimization. Denote the weights as and then the MultiGradientOptimizer will optimize by using update rule:
The test for this class illustrates the expected behavior.

virtual::itk::LightObject::Pointer itk::MultiGradientOptimizerv4::CreateAnother | ( | void | ) | 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::GradientDescentOptimizerv4.
virtual SizeValueType itk::MultiGradientOptimizerv4::GetCurrentIteration | ( | ) | const [virtual] |
Get the current iteration number.
Reimplemented from itk::GradientDescentOptimizerBasev4.
const MetricValuesListType& itk::MultiGradientOptimizerv4::GetMetricValuesList | ( | ) | const |
Get the list of metric values that we produced after the multi-objective search.
virtual const char* itk::MultiGradientOptimizerv4::GetNameOfClass | ( | ) | const [virtual] |
Run-time type information (and related methods).
Reimplemented from itk::GradientDescentOptimizerv4.
virtual const SizeValueType& itk::MultiGradientOptimizerv4::GetNumberOfIterations | ( | ) | [virtual] |
Get the number of iterations.
Reimplemented from itk::GradientDescentOptimizerBasev4.
Get the list of optimizers currently held.
virtual const StopConditionType& itk::MultiGradientOptimizerv4::GetStopCondition | ( | ) | [virtual] |
Get stop condition enum

Mutex lock to protect modification to the reference count
Reimplemented from itk::GradientDescentOptimizerv4.
virtual void itk::MultiGradientOptimizerv4::PrintSelf | ( | std::ostream & | os, |
Indent | indent | ||
) | const [protected, virtual] |
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::GradientDescentOptimizerv4.
virtual void itk::MultiGradientOptimizerv4::ResumeOptimization | ( | ) | [virtual] |
Resume the optimization. Can be called after StopOptimization to resume. The bulk of the optimization work loop is here.
Reimplemented from itk::GradientDescentOptimizerv4.
virtual void itk::MultiGradientOptimizerv4::SetNumberOfIterations | ( | SizeValueType | _arg | ) | [virtual] |
Set the number of iterations.

Set the list of optimizers to combine
virtual void itk::MultiGradientOptimizerv4::StartOptimization | ( | void | ) | [virtual] |
Begin the optimization
Reimplemented from itk::GradientDescentOptimizerv4.
virtual void itk::MultiGradientOptimizerv4::StopOptimization | ( | void | ) | [virtual] |
Stop optimization. The object is left in a state so the optimization can be resumed by calling ResumeOptimization.
