sc::LineOpt - The LineOpt abstract class is used to perform one dimensional optimizations.
#include <opt.h>
Inherits sc::Optimize.
Inherited by sc::Backtrack, and sc::MCSearch.
LineOpt (StateIn &)
LineOpt (const Ref< KeyVal > &)
void save_data_state (StateOut &)
Save the base classes (with save_data_state) and the members in the same order

Applies a nonlinear transform. double decrease_factor ()
Returns factor for sufficient decrease test. double set_decrease_factor
(double factor)
Sets factor for sufficient decrease test.

The LineOpt abstract class is used to perform one dimensional optimizations.
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.
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.
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.
