What is AI

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

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 runwhen they
  saw you coming. After all, theyve just seen you
  waste three of their pals. Trouble is, thats
  boring. Theyd 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 thats real AI!

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.

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

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.

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 arent 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
