'''Event-driven molecular dynamics''' is often used to simulate [[Idealised models#'Hard' models | hard]] or [[Idealised models#Piecewise continuous models |  piecewise continuous models]] (rather than the more familiar ''time-driven'' [[molecular dynamics]] used for [[Idealised models#'Soft' models | soft models]]). An example of an ''event'' is a collision. One of the first examples of the use of such an algorithm was in the study of [[Hard disk model | hard disks]] in 1959 <ref>[http://dx.doi.org/10.1063/1.1730376    B. J. Alder and T. E. Wainwright "Studies in Molecular Dynamics. I. General Method", Journal of Chemical Physics '''31''' pp. 459-466 (1959)]</ref>.
