The Turing test is used to determine whether or not a machine is capable of thinking like a human. IT was developed by Alan Turing in 1950.

The Turing Test is like an interrogation game between three players. There is an interrogator who is a human. He has to interrogate two other players- one computer and one human. The interrogator has to figure out which one is a computer by asking questions. The computer has to do its best to make itself HARD to be distinguished from the human. The machine will be considered intelligent if it makes it hard to be distinguished from the human.

Consider the following SCENARIO: Player A is a computer, Player B is a human, and Player C is a questioner. The interrogator is aware that one of them is a robot, but he needs to figure out which one. Since all players communicate via keyboard and screen, the outcome is UNAFFECTED by the machine's capacity to transform words into SPEECH. The exam result is determined not by the number of correct answers, but by how closely the responses resemble those of a human. The computer is permitted to do whatever it can to force the interrogator to make a false identification.

The question-answer session can be like this-

Interrogator: Are you a computer?

Player A (computer)- No.

Interrogator: Multiply two huge numbers, such as (256896489*456725896).

Player A- After a long delay, he gives the incorrect answer.

If an interrogator is unable to distinguish between a machine and a human in this game, the computer passes the test, and the machine is said to be intelligent and capable of thinking like a human. This game is POPULARLY called ‘imitation game’.
