Abstract:
A method for controlling performance of a machine used by a user, which machine is operable by causative signals, the performance of which machine is indicatable by indicative signals, said machine being controlled by a control system comprising:a control module programmed to output the causative signals when receiving per-selected signals, wherein the input-output relationship of the control module is regulated by coefficients; anda genetic algorithm unit programmed to select fitted coefficients based a selection signal when using coefficients as genes, wherein the selected fitted coefficients replace the coefficients used in the control module to update its input-output relationship;said method comprising the steps of:(a) outputting the causative signals from the control module to the machine when the control module receives per-selected signals;(b) selecting a selection signal from the group consisting of: (i) a selection signal inputted directly by the user in response to the performance of the machine based on its indicative signals; (ii) a selection signal expressed numerically by analyzing the user's reaction to the performance of the machine based on its indicative signals; and (iii) a pre-set target value;(c) selecting fitted coefficients by the genetic algorithm unit based on the selected selection signal; and(d) replacing the coefficients used in the control module to update its input-output relationship to control the machine.
