Member Function Documentation

◆ save_data_state()

void sc::NewtonOpt::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.

◆ update()

int sc::NewtonOpt::update ( )
virtual

Take a step.

Returns 1 if the optimization has converged, otherwise 0.

Implements sc::Optimize.
