Inherits sc::DFPUpdate.
BFGSUpdate (StateIn &)
BFGSUpdate (const Ref< KeyVal > &)
void save_data_state (StateOut &)
Save the base classes (with save_data_state) and the members in the same order
that the StateIn CTOR initializes them. void update (const
RefSymmSCMatrix &ihessian, const Ref< Function
> &, const RefSCVector &xnew, const RefSCVector
&gnew)
The DFPUpdate class is used to specify a Broyden, Fletcher, Goldfarb, and Shanno hessian update scheme.
This hessian update method is the recommended method for use with QNewtonOpt objects.
Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data.
Reimplemented from sc::DFPUpdate.
