Additional Inherited Members¶

void sc::SteepestDescentOpt::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::Optimize.

int sc::SteepestDescentOpt::update () [virtual]¶

Take a step. Returns 1 if the optimization has converged, otherwise 0.

Implements sc::Optimize.
