1. A computer-implemented method for manufacturing or controlling a technical system, the method comprising:
(a) inputting a sample of parameter sets suitable for manufacturing or controlling the technical system, with a feasibility identifier assigned to each of the parameter sets, wherein the feasibility identifier marks each parameter set either as technically feasible, if the parameter set meets given system criteria of the technical system, or technically non-feasible, if the parameter set does not meet the given system criteria, or erroneous, if an evaluation of the parameter set using a computerized simulation results in an error, in terms of manufacturing or controlling the technical system;
(b) generating a computerized surrogate model for the technical system based on the respective parameter sets of the sample, which are marked as technically feasible, but not on erroneous and not on non-feasible parameter sets, by means of a regression method;
(c) determining an optimized parameter set based on the surrogate model by means of a computerized optimization method; and
(d) outputting the optimized parameter set for manufacturing or controlling the technical system.
