For numerous applications, the computation and provision of exact derivative information plays an important role for optimizing the considered system. This paper introduces the technique of algorithmic differentiation, a method to compute derivatives of arbitrary order within working precision. This derivative information will be combined with a calculus-based optimization algorithm to optimize a non-trivially shaped laser pulse which coherently steers the electron dynamics in a semiconductor quantum wire. Numerical results illustrating the cost for the derivative computation and the optimization process are presented and discussed.
► Steering the electron dynamics in nanostructures with shaped laser pulses poses a formidable optimization problem.
► We present a mathematical framework for the optimized control.
► Calculus-based optimization methods and genetic algorithms are discussed.
► The performance of the optimization processes are analyzed in detail and compared.
