Inheritance diagram for sc::HessianUpdate:
Public Member Functions | |
HessianUpdate (StateIn &) | |
HessianUpdate (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. | |
virtual void | update (const RefSymmSCMatrix &hessian, const Ref< Function > &, const RefSCVector &xnew, const RefSCVector &gnew)=0 |
virtual void | set_inverse () |
virtual void | apply_transform (const Ref< NonlinearTransform > &) |
Protected Attributes | |
int | inverse_hessian_ |
It is used, for example, by QNewtonOpt objects. Based on the value of inverse_hessian_ x and g may be reversed (see Schlegel, Ab initio Methods in Quantum Chemistry I, 1987, p 10).
void sc::HessianUpdate::save_data_state | ( | StateOut & | ) | [virtual] |
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::SavableState.
Reimplemented in sc::DFPUpdate, sc::BFGSUpdate, and sc::PowellUpdate.
