ElecMinimizer (Everything &e) | |
void | step (const ElecGradient &dir, double alpha) |
Move the state in parameter space along direction dir with scale alpha. | |
double | compute (ElecGradient *grad, ElecGradient *Kgrad) |
Returns the objective function at the current state and store the gradient in grad and preconditioned gradient in Kgrad, if non-null. | |
bool | report (int iter) |
void | constrain (ElecGradient &) |
Constrain search directions to the space of free directions for minimize. | |
double | sync (double x) const |
All processes minimize together; make sure scalars are in sync to round-off error. | |
Public Member Functions inherited from Minimizable< ElecGradient > | |
virtual double | safeStepSize (const ElecGradient &dir) const |
Override to return maximum safe step size along a given direction. Steps can be arbitrarily large by default. | |
double | minimize (const MinimizeParams ¶ms) |
Minimize this objective function with algorithm controlled by params and return the minimized value. | |
void | fdTest (const MinimizeParams ¶ms) |
Variational total energy minimizer for electrons.
|
virtual |
Override for optional processing/reporting after each/every few iterations It should return whether the state was modified
