hessian update scheme.
Constructor & Destructor Documentation
- sc::DFPUpdate::DFPUpdate (const Ref< KeyVal > &)
- The KeyVal constructor reads the following keywords:.
- xprev
The previous coordinates can be given (but is not recommended). The default is none.
- gprev
The previous gradient can be given (but is not recommended). The
default is none.
Member Function Documentation
- void sc::DFPUpdate::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::HessianUpdate.
- Reimplemented in sc::BFGSUpdate.
