1 What is AI  An attempt to imitate human reactions by scripting reactions to happen when a certain cause is brought about.

2 What is AI?  Fundamentally Humans and Computers think differently Computers strictly use logic in making decisions; many decisions are based off of true/false statements Humans think part logically, part intuitively, part common sensibly

3 Weak AI  As used in games, it can be applied to opponent players These can have rules hard coded into them They can learn about their environment There can be a combination of both  One of the challenges of a game developer is that people may want a game to be a challenge but not too human

4 Weak AI My favorite quote from the research done by the College of New Jersey to emphasize that point  “… in a shoot-em-up like Quake, the ‘smart’ think for a creature to do would be to run…when they saw you coming. After all, they’ve just seen you waste three of their pals. Trouble is, that’s boring. They’d just go and hide in a corner and shoot you in the back the first chance they get… the game would be reviewed as unfair and bad gameplay… but hold on that’s real AI!”

5 Weak Artificial Intelligence  What is considered weak A.I.? Machines acting as if they were intelligent, but simply on the basis of a complex set of rules. Weak A.I. does not have the strength of having feelings or senses. Weak A.I. has some type of "thinking" features can be added to computers to make them more

6 Weak A.I. (Cont.)  Some kind of thinking-like feature can be added to a computer to make them more useful for individuals in everyday life.  When weak artificial intelligence is added to computers, they act as if they are intelligent and can simulate some kind of human cognition, for example voice recognition.

7 The Turing Test  The 'Turing Test' is an experiment suggested by mathematician Alan Turing in his 1950 paper Computing Machinery and Intelligence. He argued that if a machine could successfully pretend to be human to a knowledgeable observer, then you certainly should consider it intelligent. In the Turing test, a judge has conversations via teletype, with two systems, one human, the other a machine. The conversations can be about anything, and proceed for a set period of time. If, at the end of this time, the judge cannot distinguish the machine from the human on the basis of the conversation, then Turing argued that we would have to say that the machine was intelligent.

8 Examples of Weak A.I.  The IBM super computer named Deep Blue tested its processing power and won several chess games against the famous chess player Gary Kasparov.  Spell check on Microsoft Word  Calculators  Game of life

9 Learning AI – Some Examples  SAL Uses a learned database of board states Both can be used with games two player games other than chess Takes a long time to learn a game  Morph Uses mathematics to find the best move to make in a game Can be use with other games with variable numbers of players New, rare experiences that come up in a game cause morph to make a bad decision

10 Strong AI  The computer has cognitive processes.  It is artificial in the sense that it is created by humans, but it is characterized by true intelligence. In other words, instead of just following instructions on how to react in a situation, the computer will react with a sense of reason.

11 Strong AI: What is it?  The emphasis need not be on what the computer being made out of what computers are made out of now. To classify it as AI is that it is made by humans. So, it could be made with biotechnology or practices other than current programming methods.

12 …And Finally, the Illustration  This little game is a demonstration version of a game I have been developing for some time now  The object of the game is to destroy the ship at the top with your ship at the bottom by shooting it (down arrow key)  Avoid fire so you aren’t destroyed (left and right arrows)

13 …And Finally, the Illustration  In relation to the topic at hand: The enemy ship “plays” back, since it has missiles,  In one player mode, it tries to stay on the opposite side of the screen from you and shoot its missiles  In two players, all the ships try to chase you down, but avoid fire The missiles have basic AI in that they chase their targets
