  • Title: Misperception influence on zero-determinant strategies in iterated Prisoner's Dilemma.
    Author: Cheng Z, Chen G, Hong Y.
    Journal: Sci Rep; 2022 Mar 25; 12(1):5174. PubMed ID: 35338188.
    Abstract:
    Zero-determinant (ZD) strategies have attracted wide attention in Iterated Prisoner's Dilemma (IPD) games, since the player equipped with ZD strategies can unilaterally enforce the two players' expected utilities subjected to a linear relation. On the other hand, uncertainties, which may be caused by misperception, occur in IPD inevitably in practical circumstances. To better understand the situation, we consider the influence of misperception on ZD strategies in IPD, where the two players, player X and player Y, have different cognitions, but player X detects the misperception and it is believed to make ZD strategies by player Y. We provide a necessary and sufficient condition for the ZD strategies in IPD with misperception, where there is also a linear relationship between players' utilities in player X's cognition. Then we explore bounds of players' expected utility deviation from a linear relationship in player X's cognition with also improving its own utility.
