Member Function Documentation

virtual void sc::LineOpt::init (RefSCVector & direction) [virtual]

Initializes the line search object. Argument is a search direction. Use of this method assumes the Optimize base class already has a function object (got it from a keyval or elsewhere).

Reimplemented in sc::MCSearch.

virtual void sc::LineOpt::init (RefSCVector & direction, Ref< Function > function) [virtual]

Initializes the line search object. First argument is a search direction, second argument is a function object to optimize. Use this method when a function must be passed to the Optimize base class.

Reimplemented in sc::MCSearch.

void sc::LineOpt::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.
