g encodes information for machine M1 and produces corresponding information for machine M2; h is the inverse function. Machine M2 is said to simulate machine M1 if it is possible to specify a translation algorithm such that, when given a program P1 for M1, it produces a corresponding program P2 for M2; further, the effect of P1 on M1 should be equivalent to the effect of
applying function g
then executing P2 on M2
then applying function h.
In symbols, P1 = h P2 g
An equally useful formulation has functions g : M1 → M2, h : M1 → M2
and the simulation criterion h P1 = P2 g
Machine simulation of this kind is generally discussed for idealized abstract machines, such as Turing machines, and for formal models of microprocessors. It provides a useful approach to defining the correctness of implementations. See also machine equivalence.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
