sc::Convergence - The Convergence class is used by the optimizer to determine when an optimization is converged.
#include <conv.h>
Inherits sc::SavableState.
Inherited by sc::MolEnergyConvergence.
Convergence (double tolerance)
Convergence (StateIn &)
Convergence (const Ref< KeyVal > &)
The KeyVal constructor reads the following keywords: 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 get_grad
(const Ref< Function > &)
Set the current gradient and displacement. virtual void get_x (const
Ref< Function > &)
virtual void set_nextx (const RefSCVector &)
virtual void reset ()
Set the current gradient and displacement to null. virtual int
converged ()
Return nonzero if the optimization has converged.
void check_conv (const char *heading, double val, double
bound, int &pass, int &fail)
void set_defaults ()

The Convergence class is used by the optimizer to determine when an optimization is converged.
The KeyVal input for Convergence is given below. Giving none of these keywords is the same as giving the following input:
conv<Convergence>: (
max_disp = 1.0e-6
max_grad = 1.0e-6
graddisp = 1.0e-6
)
The KeyVal constructor reads the following keywords:
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.
