Noniterative methods, like the zeroth- or first-order approximation, are used to solve the optimal quantum control problem. Zeroth-order methods without feedback from the objective are generously inadequate. Numerical tests show that first-order approximation give good accuracy in several cases, but the modified first-order method gives better results even for difficult systems.
