WebbAs mentioned above, some of the very earliest small Turing machines were poly- nomial time simulators. Subsequently, attention turned to the smaller, but ex- ponentially slower, 2-tag simulators given by Minsky, Rogozhin and others. Recently [65] we have given small machines that are eﬃcient polynomial time simulators. WebbB1. To prove by hand that a non-halting machine that resists the computational proof does not halt. B2.

"Webb28 okt. 2007 · Alex Smith’s encoding for the 2,3 Turing machine clearly isn’t going to be practical (and wasn’t intended to be). But one of the lessons of modern technology is that once one knows something is in principle possible, it tends to be just a matter of time before it can be reduced to practice.

WebbWhen we consider machines that decide a word according to the decision taken by the lexicographically first shortest computation, we obtain a new characterization of PNP. A series of other ways of deciding a language with respect to the shortest computations of a Turing machine are also discussed.

WebbAdmittedly, Turing machines are a terrible model for thinking about fast computation; simple operations that take constant time in the standard random-access model can require arbitrarily many steps on a Turing machine. Worse, seemingly minor variations in the precise deﬁnition of “Turing machine” can have signiﬁcant impact on problem ... WebbAnswer (1 of 5): Despite some previous misleading answers, your question is very relevant and I have devoted some of my research to it myself. You probably meant how small a universal Turing machine can be, and not how small any Turing machine can be. The answer to the latter is pretty small, and...
