sc::Optimize - The Optimize class is an abstract base class for classes that find the extreme points of Function's.
#include <opt.h>
Inherits sc::SavableState.
Inherited by sc::EFCOpt, sc::GDIISOpt, sc::LineOpt, sc::NewtonOpt, sc::QNewtonOpt, and sc::SteepestDescentOpt.

Restore the state of a Function object. Optimize (const

The KeyVal constructor reads the following information: 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 int optimize

Do the optimization. void set_checkpoint ()
Set up for checkpointing. void set_checkpoint_file (const char *)
void set_function (const Ref< Function > &)
Set the function to be optimized. void set_max_iterations (int)
Set the iteration limit. virtual void init ()
Initialize the optimizer. virtual int update ()=0

The Optimize class is an abstract base class for classes that find the extreme points of Function's.
The KeyVal constructor reads the following information:
Do the optimization. Returns nonzero if the optimization is complete.
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::SavableState.
Reimplemented in sc::SteepestDescentOpt, sc::QNewtonOpt, and sc::LineOpt.
Take a step. Returns 1 if the optimization has converged, otherwise 0.
Implemented in sc::SteepestDescentOpt, sc::QNewtonOpt, sc::Backtrack, sc::NewtonOpt, sc::MCSearch, sc::GDIISOpt, and sc::EFCOpt.
