Claim:
1. A method for simultaneous optimization of a group of N electromagnetic pulses P (j) with N>1, wherein the pulses are used for manipulation of system states of a spin system using an optimal control based algorithm, the method comprising the steps of: a) choosing N electromagnetic initial pulses P b) calculating N trajectories of the system states of the spin system experiencing the pulses P c) defining a quality factor φ that is at least dependent on final system states at a point in time T d) calculating costates λ e) calculating N trajectories of the costates λ f) calculating gradients of the quality factor φ with respect to the controls ν g) adding gradients to the controls ν h) repeating steps b) to g) using the updated controls ν i) implementing the electromagnetic pulses following step h).
