Public Member Functions

 InvertKS (const RadialFunctionR &nTarget)
 Initialize for a given target electron density nTarget.
 
RadialFunctionR getTau ()
 Get the orbital KE density.
 
void step (const diagMatrix &dV, double alpha)
 Move the state in parameter space along direction dir with scale alpha.
 
double compute (diagMatrix *E_V, diagMatrix *KE_V)
 Returns the objective function at the current state and store the gradient in grad and preconditioned gradient in Kgrad, if non-null.
 
diagMatrix precondition (const diagMatrix &grad)
 
- Public Member Functions inherited from Minimizable< diagMatrix >
virtual bool report (int iter)
 
virtual void constrain (diagMatrix &)
 Constrain search directions to the space of free directions for minimize.
 
virtual double sync (double x) const
 Override to synchronize scalars over MPI processes (if the same minimization is happening in sync over many processes)
 
virtual double safeStepSize (const diagMatrix &dir) const
 Override to return maximum safe step size along a given direction. Steps can be arbitrarily large by default.
 
double minimize (const MinimizeParams &params)
 Minimize this objective function with algorithm controlled by params and return the minimized value.
 
void fdTest (const MinimizeParams &params)
