In this work we present an efficient approach for the calculation of the sensitivities in the case of unsteady problems like the compressible high‐speed flows. The sensitivities are of a known response with respect to the initial conditions. If the number of parameters is large, the adjoint method is preferred since the cost of computing the sensitivities is independent of the number of design parameters.
