Summary on Grant Application Form
The use of game theoretic techniques in computer science is becoming ever more prevalent. One reason for this is that in many of the systems we want to build, participants cannot be assumed to be benevolent: instead, they must be assumed to be rational agents, acting in pursuit of their own personal goals. For such systems, game theory provides a natural analytical framework. In our work, we are interested in the automated analysis of such systems using techniques for model checking, which over the past two decades have proved to be enormously influential. In model checking, the idea is to express desirable system properties as logical formula, and then to check whether these properties actually hold of the given system. A key problem if we want to extend existing verification techniques to game theoretic settings is that the formalisms used in model checking do not allow us to directly represent the preferences or utilities of players (i.e., their goals). This project is directed at this problem. The basic idea is that we can use a formalism known as Lukasiewicz logic to express the "utility function" for players, which represent their preferences. Lukasiewicz logic is a non-classical, multiple-valued logic which has the attractive property that Lukasiewicz formulae can represent a very rich class of utility functions -- much richer than is possible using classical logic. The project will lay the theoretical groundwork for this new and exciting class of logically-specified games, and has the potential to greatly enrich the class of systems for which logic-based automated analysis techniques can be applied.
