Abstract
In this paper, we re-explain four types of players’ rationality from the viewpoint of strategy-choosing regret, and we provide a unified logic of epistemic characterization of the four iterated elimination algorithms IESD (Iterated Elimination Strictly Dominated strategy), Rationalizablity (also called iterated elimination strategies that are never best responses), IA (Iterated Admissibility) and IERS (Iterated Elimination Regret-dominated Strategy). The unified characterization extends van Benthem’s work of linking game theory with epistemic logic and provides further insights into exploring the rationale of these iterated eliminating algorithms. In addition, to clarify the proof-theoretic principles assumed in players’ reasoning, we also develop an axiomatic presentation for our results.
