### Additional Inherited Members

## Member Function Documentation

### void sc::SteepestDescentOpt::init ()` [virtual]`

Initialize the optimizer.

Reimplemented from **sc::Optimize**.

### 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**.
