Uncertainty in Abstract Argument Games: A Case Study on the Game for the Grounded Extension

The paper argues for the equipment of argument games with richer game-theoretic features. Concretely, it tackles the question of what happens to argument games when proponent and opponent are uncertain about the attack graph upon which they are playing. This simple sort of uncertainty, we argue, caters for the modeling of several strategic phenomena of real-life arguments. Using the argument game for the grounded semantics as a case study, the paper studies the impact of uncertainty over the ability of argument games to deliver adequacy with respect to their corresponding semantics.
