Lecture #9 looked at some basic game theory as a mechanism for agents to make decisions when they are in a multiagent environment.
Notes are available in two formats:
The textbook covers some game theory in Section 17.5, pages 666--674. The presentation there differs quite a lot from mine.
A nice paper that relates to the material in the lecture is:
J. K. Goeree and C. A. Holt Ten Little Treasures of Game Theory, and Ten Intuitive Contradictions American Economic Review, December 2001, 91, 1402-1422.
Syadu pointed out that this excellent book:
Y. Shoham and K. Leyton-Brown Multiagent Systems Algorithmic, Game-Theoretic, and Logical Foundations, Cambridge University Press, 2009.is both available as a free download and has a good chapter on basic game theory.
