2025年2月5日 · Turing Machines (TM) play a crucial role in the Theory of Computation (TOC). They are abstract computational devices used to explore the limits of what can be computed. Turing Machines help prove that certain languages and problems have no algorithmic solution.

Visualize and simulate Turing machines as animated state diagrams. Create and share your own machines using a simple format. Examples and exercises are included.

The Turing Machine A Turing machine consists of three parts: A finite-state control that issues commands, an infinite tape for input and scratch space, and a tape head that can read and write a single tape cell. At each step, the Turing machine writes a symbol to the tape cell under the tape head, changes state, and

A Turing machine is a 7-tuple where: 1. is a set of states, 2. is a finite set of allowable tape symbols, 3. is a symbol from called blank, 4. , , 5. ( may be undefined on some arguments), 6. is the start state, 7. is the set of final states. Turing Machines – p.18/37

Mechanical Diagram of Turing Machine. A Turing machine consists of three main parts: an input tape, a read-write head, finite control. The input tape contains the input alphabets. It has an infinite number of blanks at the left and right side of the input symbols.
