Abstract: A device receives an initial model of a system and information that identifies a solving technique to be used to solve a mathematical problem associated with the initial model. The initial model includes an initial transfer function that describes a relationship between an input to and an output from the system. The device determines an error associated with the solving technique, resulting in an inaccurate solution to the mathematical problem. The device generates an adjusted model, based on the initial model and the error, that includes an adjusted transfer function, based on the initial transfer function, or an adjusted input to the system, based on the input to the system. The device applies the solving technique to the adjusted model, to generate a result that includes a more accurate solution to the mathematical problem than applying the solving technique to the initial model, and outputs or stores the result.
