AI forms a vital branch of computer science, dealing with intelligent behavior, learning and adaptation in machines. Research in AI is concerned with producing machines to automate tasks requiring intelligent behavior.
Examples include control, planning and scheduling, the ability to answer diagnostic and consumer questions, handwriting, speech, and facial recognition.
As such, it has become an engineering discipline, focused on providing solutions to real life problems.
AI systems are now common-use in economics, in medicine, in engineering and in the military, and are built into many common software applications, traditional strategy games like computer chess and other video games.
