The Turing Test, proposed by British mathematician and computer scientist Alan Turing in 1950, is a measure of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. In the test, a human evaluator interacts with both a machine and a human without knowing which is which, through text-based communication. If the evaluator cannot reliably distinguish the machine from the human based on their responses, the machine is considered to have passed the Turing Test, demonstrating the capability to simulate human-like intelligence.
