refimprove date August 2010 In computational complexity , a field of computer science , random access Turing machines are an extension of Turing machine s used to speak about small complexity classes, especially for classes using logarithmic time, like DLOGTIME and the LH complexity Logarithmic Hierarchy . Definition On a random access Turing machine, there is a special pointer tape of logarithmic space accepting a binary vocabulary. The Turing machine has a special state such that when the binary number on the pointer tape is p , the Turing machine write on the working tape the p th symbol of the input. This lets the Turing machine read any letter of the input without taking time to move over the entire input. This is mandatory for complexity classes using less than linear time. References N.

In a standard n tape Turingmachine, n heads move independently along n tracks. In a n track Turingmachine, one head reads and writes on all tracks simultaneously. A tape position in a n track TuringMachine contains n symbols from the tape alphabet.

turing In computability theory , a probabilistic Turingmachine is a non deterministic Turingmachine which randomly chooses between the available transitions at each point according to some probability distribution . In the case of equal probabilities for the transitions, it can be defined as a deterministic Turingmachine having an additional write instruction where the value of the write is uniform distribution discrete uniformly distributed in the TuringMachine s alphabet generally, an equal likelihood of writing a 1 or a 0 on to the tape. Another common reformulation is simply a deterministic Turingmachine with an added tape full of random bits called the random tape . As a consequence, a probabilistic Turingmachine can unlike a deterministic TuringMachine have stochastic results on a given input and instruction state machine, it may have different run times, or it may not halt at all further, it may accept an input in one execution and reject the same input in another execution. Therefore the notion of acceptance of a string by a probabilistic Turingmachine can be defined in different ways.
