Specialty Definition: NONDETERMINISTIC TURING MACHINE

DomainDefinition

Computing

Nondeterministic Turing Machine A normal (deterministic) Turing Machine that has a "guessing head" - a write-only head that writes a guess at a solution on the tape first, based on some arbitrary internal algorithm. The regular Turing Machine then runs and returns "yes" or "no" to indicate whether the solution is correct. A nondeterministic Turing Machine can solve nondeterministic polynomial time computational decision problems in a number of steps that is a polynomial function of the size of the input (1995-04-27). Source: The Free On-line Dictionary of Computing.

Math

A Turing machine which has more than one next state for some combinations of contents of the current cell and current state. An input is accepted if any move sequence leads to acceptance. (references)
