Great Expectations. Part II: Generalized Expected Utility as a Universal Decision Rule
Francis C. Chu, Joseph Y. Halpern
Many different rules for decision making have been introduced in the literature. We show that a notion of generalized expected utility proposed in Part I of this paper is a univers…
Great Expectations. Part I: On the Customizability of Generalized Expected Utility
Francis C. Chu, Joseph Y. Halpern
We propose a generalization of expected utility that we call generalized EU (GEU), where a decision maker's beliefs are represented by plausibility measures, and the decision maker…
On the NP-completeness of Finding an Optimal Strategy in Games with Common Payoffs
Francis Chu, Joseph Y. Halpern
Consider a very simple class of (finite) games: after an initial move by nature, each player makes one move. Moreover, the players have common interests: at each node, all the play…
Least expected cost query optimization: an exercise in utility
Francis C. Chu, Joseph Y. Halpern, Praveen Seshadri
We identify two unreasonable, though standard, assumptions made by database query optimizers that can adversely affect the quality of the chosen evaluation plans. One assumption is…
A decision-theoretic approach to reliable message delivery
Francis C. Chu, Joseph Y. Halpern
We argue that the tools of decision theory need to be taken more seriously in the specification and analysis of systems. We illustrate this by considering a simple problem involvin…
