==Knock control==
The objective of knock control strategies is to attempt to optimize the trade-off between protecting the engine from damaging knock events and maximizing the engine's output torque. Knock events are an independent random process.<ref>{{Cite journal|last1=Jones|first1=J. C.

A single time history simulation or experiment of knock control methods are not able to provide a repeatable measurement of controller's performance because of the random nature of arriving knock events. Therefore, the desired trade-off must be done in a [[stochastic]] framework which could provide a suitable environment for designing and evaluating different knock control strategies performances with rigorous statistical properties.{{Citation needed|date=December 2023}}
