LatticeMinimizer (Everything &, bool dynamicsMode=false, bool statP=false, bool statStress=false) | |
void | step (const LatticeGradient &dir, double alpha) |
Move the state in parameter space along direction dir with scale alpha. | |
double | compute (LatticeGradient *grad, LatticeGradient *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 (LatticeGradient &) |
Constrain search directions to the space of free directions for minimize. | |
double | safeStepSize (const LatticeGradient &dir) const |
Override to return maximum safe step size along a given direction. Steps can be arbitrarily large by default. | |
double | sync (double x) const |
All processes minimize together; make sure scalars are in sync to round-off error. | |
double | minimize (const MinimizeParams ¶ms) |
minor addition to Minimizable::minimize to invoke charge analysis at final positions | |
int | nFree () |
number of free lattice directions | |

double | minimize (const MinimizeParams ¶ms) |
Minimize this objective function with algorithm controlled by params and return the minimized value. | |
void | fdTest (const MinimizeParams ¶ms) |
Lattice minimizer.
|
virtual |
Override for optional processing/reporting after each/every few iterations It should return whether the state was modified
