Detailed Description
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.
Member Function Documentation
◆ save_data_state()
|
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::DFPUpdate.
The documentation for this class was generated from the following file:
