Research output: Contribution to journalConference articlepeer-review


In the approach to the inverse problems, based on the sensitivity operators, the inverse problem is transformed into the family of quasi-linear operator equations. The sensitivity operator is constructed of the ensemble of the adjoint problem solutions corresponding to different adjoint problems source functions. Hence, from the theoretical point of view, sensitivity operator-based algorithms can be efficiently parallelized. The paper's objective is to carry out the experimental study of the algorithm computation time for the different number of computation cores.
