Counter Machine Models

This page supplements counter machine.

Although some authors use the name "register machine" synonymously with "counter machine", this article will give details and examples of only of the most primitive species – the "counter machine" – of the genus "register machine."

Within the species "counter machine" there are a number of varieties: the models of Hermes (1954), Kaphengst (1957), Ershov (1958), Peter (1958), Minsky (1961) and Minsky (1967), Melzak (1961), Lambek (1961), Shepherdson and Sturgis (1963), and Schönhage (1980). These models will be described in more detail in the following.

Famous quotes containing the words models, counter and/or machine:

    French rhetorical models are too narrow for the English tradition. Most pernicious of French imports is the notion that there is no person behind a text. Is there anything more affected, aggressive, and relentlessly concrete than a Parisan intellectual behind his/her turgid text? The Parisian is a provincial when he pretends to speak for the universe.
    Camille Paglia (b. 1947)

    The technological landscape of the present day has enfranchised its own electorates—the inhabitants of marketing zones in the consumer goods society, television audiences and news magazine readerships... vote with money at the cash counter rather than with the ballot paper at the polling booth.
    —J.G. (James Graham)

    Man is a beautiful machine that works very badly.
    —H.L. (Henry Lewis)
