Detailed Description

Limited memory Broyden Fletcher Goldfarb Shannon minimization with simple bounds.

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

See also the documentation in Numerics/lbfgsb.c

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.

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

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

Print out internal state

Reimplemented from itk::LBFGSOptimizerBasev4< vnl_lbfgsb >.

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

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.
