“The science and engineering of making intelligent machines, especially intelligent computer programs.” ( John McCarthy)
Intelligence has been a topic of investigation for many centuries, dating back to the ancient Greek philosophers. But it is fair to say that it is a topic of a more scientific approach for just about 60 years. Crucial in this respect is the emergence of artificial intelligence (AI) in the mid 20th century. As the word “artificial” suggests, AI aimed and aims not only to understand intelligence but also to build intelligent devices.
