Game trees (or extensive-form games) were first defined by von Neumann
and Morgenstern in 1944. In this paper we examine the use of game tre
es for representing Bayesian decision problems. We propose a method fo
r solving game trees using local computation. This method is a special
case of a method due to Wilson for computing equilibria in 2-person g
ames. Game trees differ from decision trees in the representations of
information constraints and uncertainty. We compare the game tree repr
esentation and solution technique with other techniques for decision a
nalysis such as decision trees, influence diagrams, and valuation netw
orks.
