Register Machine

In mathematical logic and theoretical computer science a register machine is a generic class of abstract machines used in a manner similar to a Turing machine. All the models are Turing equivalent.

Famous quotes containing the words machine and/or register:

    The momentary charge at Balaklava, in obedience to a blundering command, proving what a perfect machine the soldier is, has, properly enough, been celebrated by a poet laureate; but the steady, and for the most part successful, charge of this man, for some years, against the legions of Slavery, in obedience to an infinitely higher command, is as much more memorable than that as an intelligent and conscientious man is superior to a machine. Do you think that that will go unsung?
    Henry David Thoreau (1817–1862)

    A funeral is not death, any more than baptism is birth or marriage union. All three are the clumsy devices, coming now too late, now too early, by which Society would register the quick motions of man.
    —E.M. (Edward Morgan)
