This article mainly introduces how the Turing machine is composed, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

The Turing machine consists of three parts: 1, the tape is divided into many squares in which symbols can be written or read; 2, a movable read-write head that can read symbols from the tape or write symbols to the tape; 3, a set of rules indicating what to do next.

The Turing machine consists of three parts:

1. The tape is divided into many squares (or "addresses") in which symbols can be written or read. Both ends of the tape have unlimited length.

two。 A movable read-write head that can read symbols from or write symbols to a tape. At any time, the read-write head is in one of a set of states.

3. A set of rules that instruct the read and write head what to do next.

The read-write head starts in a specific starting state and stops on a specific grid.

At each step, the read-write head reads the symbols in the current grid. Then the read-write head acts in accordance with the rules according to the read symbol and the current state of the read-write head.

Rules determine what symbol the read-write head writes in the current grid (replacing the current symbol); whether the read-write head moves to the right or left or stops; and what is the new state of the read-write head. If the read-write head goes into a stop state, the machine will stop.

The input of a Turing machine is a collection of symbols written on the tape before the machine starts. The output is the set of symbols left on the tape after downtime.

Thank you for reading this article carefully. I hope the article "how is the Turing machine made up" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
