NAME

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

SYNOPSIS

#include <opt.h> Inherits sc::Optimize. Inherited by sc::Backtrack, and sc::MCSearch. Public Member Functions 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 that the StateIn CTOR initializes them. virtual void init (RefSCVector &direction) Initializes the line search object. virtual void init (RefSCVector &direction, Ref< Function > function) Initializes the line search object. void apply_transform (const Ref< NonlinearTransform > &) 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. Protected Member Functions int sufficient_decrease (RefSCVector &step) Protected Attributes double decrease_factor_ RefSCVector initial_x_ double initial_value_ RefSCVector initial_grad_ RefSCVector search_direction_ Ref< Function > function_ Additional Inherited Members Detailed Description The LineOpt abstract class is used to perform one dimensional optimizations. 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. Author Generated automatically by Doxygen for MPQC from the source code.
