Mathematical structure of payoff control in repeated games
Game theory is a mathematical framework describing rational decision making of multiple agents. Recently, in repeated games, a class of strategies, called “zero-determinant strategies”, was discovered, which unilaterally control payoffs of players. Many researchers have expanded the range of application of zero-determinant strategies. More recently, I proposed an extended version of zero-determinant strategies, which enables more complicated payoff control, such as control of conditional expectations of payoffs. However, what we can do by extended zero-determinant strategies is still not clear. In this research, I investigate properties of extended zero-determinant strategies in social dilemma games. Particularly, I investigate relation between extended zero-determinant strategies and equilibrium strategies, and want to elucidate their significance in social science and evolutionary biology.


Thank you for investing in a subject that seems to be of no use to us. We hope to conduct research that will be interesting to people outside our field of expertise.
