Abstract

This paper studies the notion of qualitative game theory in the context of multi-agent decision making. We use logic programs with ordered disjunction (LPODs), invented by Brewka, as representation and reasoning language for strategic form of games. Structure and rules of a game are represented as a LPODin which preferences of players are encoded as ordered disjunctive rules. Solution of a game is defined in terms of equilibria such that preferred answer sets of a LPOD representing a game correspond exactly to respective types of equilibria of the game. We also discuss games in which rules have been changed or players are wrong informed about the rules of a game.
