1. A method of controlling an output of a computing system, comprising: providing, via a processing system, a set of adjustable inputs to the computing system; observing, via the processing system, while in operation, performance metrics associated with an output of the computing system; identifying, via the processing system, adjustable inputs from the set of adjustable inputs which most affect at least a selected one of the performance metrics, the identifying comprising applying a statistical analysis to the observed performance metrics to identify the adjustable inputs; and adjusting, via the processing system, while in operation, only the identified adjustable inputs to achieve a desired value of the at least selected one perfbrrnance metric without adjusting the adjustable inputs that are not identified but are provided to the computing system.
