What is a Turing Machine having Probabilistic Automation?

WebbA probabilistic Turing machine is a Turing machine with the ability to make decisions based on the outcomes of unbiased coin tosses. The partial function computed by a probabilistic machine is defined by assigning to each input the output which occurs with probability greater than $\frac {1} {2}$. With this definition, only partial recursive ... WebbIn general, if you have a probabilistic Turing machine P solving some decision problem, you can always simulate it deterministically by running P for every possible value of the randomness and outputting the majority answer of P. Therefore, no probabilistic Turing machine can solve an undecidable decision problem. games like a grim chaseIn theoretical computer science, a probabilistic Turing machine is a non-deterministic Turing machine that chooses between the available transitions at each point according to some probability distribution. As a consequence, a probabilistic Turing machine can—unlike a deterministic Turing Machine—have … Visa mer A probabilistic Turing machine is a type of nondeterministic Turing machine in which each nondeterministic step is a "coin-flip", that is, at each step there are two possible next moves and the Turing machine probabilistically … Visa mer As a result of the error introduced by utilizing probabilistic coin tosses, the notion of acceptance of a string by a probabilistic Turing machine can be defined in different ways.

If you never make use of this power, you get a deterministic Turing machine. In a similar fashion, a non-deterministic Turing machine is allowed to make guesses, but if it doesn't it is just a deterministic Turing machine.

WebbAs it stands, Turing machines are deterministic machines. Since probabilistic machines have received wide interest in recent years [1], [8], it is natural to inquire about what will happen if random elements are allowed in a Turing machine. This has led the author to consider probabilistic Turing machines (PTM) in an earlier paper [9].
