PetscErrorCode TaoLineSearchGetNumberFunctionEvaluations(TaoLineSearch ls, PetscInt *nfeval, PetscInt *ngeval, PetscInt *nfgeval)
Not Collective
Input Parameter#
- ls - the - TaoLineSearchcontext
Output Parameters#
- nfeval - number of function evaluations 
- ngeval - number of gradient evaluations 
- nfgeval - number of function/gradient evaluations 
Note#
If the line search is using the Tao objective and gradient
routines directly (see TaoLineSearchUseTaoRoutines()), then the Tao
is already counting the number of evaluations.
