 What is [Game] A.I.?
 Plus: A Couple Fundamental Truths
 Where does A.I. Live?
 Further Thoughts
WHAT IS [GAME] A.I.?
A.I. = Artificial Intelligence
Generally
 Make computers smart (primary)
 Make computers think like humans (secondary)
Early A.I.
“Within a generation ... the problem of creating
'artificial intelligence' will substantially be solved.”
- Marvin Minsky 1967
“Machines will be capable, within twenty years, of
doing any work a man can do.”
- Herbert Simon 1965
Fundamental Truth:
The hard stuff is easy, and the easy stuff is hard

But What is Game A.I.?
Point 1
AI is about making computers smart.
Game AI is about making computers fun.
Smart is often not fun.
Fun is often not smart.
Point 2
Game AI is tightly interwoven with Game Design
AI is the gameplay.
1. AI coders need great design intuition, OR
2. Designers need to be able to code, OR
3. We need great tools for designers to express
behavior
Point 3
Game AI benefits from lots and lots of content.
If it looks and moves right, players think it’s smart.
If it looks or moves wrong, players think it’s dumb.
Fundamental Truth:
The hard stuff is easy, and the easy stuff is hard
Fundamental Truth:
90% of the effort is spent on the “easy” stuff.

CONCLUSIONS
Why I Do This
AI is Applied Research
Wide variety of challenges
Central to the player experience
History Repeats Itself
Game AI is recapitulating Academic AI
The Field is Fragmenting
Incorporating more statistical techniques
