What is the Turing test, and how is it used to evaluate the intelligence of AI systems?

The Turing test is a measure of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. It was proposed by Alan Turing in 1950, and its objective was to answer the question, "Can machines think?" The test is named after Alan Turing, who is widely regarded as the father of modern computer science.
