Claim One:
1. A method for controlling and/or regulating a technical system in a computer-assisted manner, in which dynamic behavior of the technical system is respectively characterized for a plurality of times by a state (s) of the technical system and an action (a) carried out on the technical system in this state, a respective action (a) at a respective time resulting in a new state (s) of the technical system at the next time, and an action sequence including actions (a) to be successively carried out on the technical system, the method comprising the steps of: a) determining a first action sequence (A 1 ) for the state (s) of the technical system at a current time (t) using an action selection rule (PO) determined by learning a data-driven model (NN) on the basis of training data comprising data records comprising known states (s) and actions (a) at a plurality of times, wherein the first action sequence comprises an initial action at the current time, the first action sequence (A 1 ) being based on an optimization criterion for operating the technical system, which is taken into account when learning the data-driven model (NN), and having a measure of quality (RE) with respect to the optimization criterion; b) searching using a numerical optimization method (PSO) for those second action sequences (A 2 ) which have a measure of quality (RE) higher than the measure of quality (RE) of the first action sequence (A 1 ), wherein the second action sequences comprise an initial action (a) at the current time, the searching starting with a number of starting action sequences which are determined by varying a number of initially provided action sequences comprising the first action sequence (A 1 ), the starting action sequences (A 2 ) having a slight variation on the basis of a priority criterion; and c) if one or more second action sequences (A 2 ) are found in step b), carrying out at least some of the successive actions (a) in the second action sequence (A 2 ) having the highest measure of quality (RE) on the technical system and otherwise carrying out at least some of the successive actions (a) in the first action sequence (A 1 ).
