Artificial intelligence

Artificial intelligence (AI) is both the intelligence of machines and the branch of computer science which aims to create it.
Artificial intelligence has successfully been used in a wide range of fields including medical diagnosis, stock trading, robot control, law, scientific discovery and toys. Frequently, when a technique reaches mainstream use it is no longer considered artificial intelligence, sometimes described as the AI effect. It may also become integrated into artificial life.
The broad classes of outcome for an AI test are:
optimal: it is not possible to perform better
strong super-human: performs better than all humans
super-human: performs better than most humans
sub-human: performs worse than most humans
For example, performance at checkers is optimalperformance at chess is super-human and nearing strong super-human and performance at many everyday tasks performed by humans is sub-human.
