The dilemma of dominance

Cyclic Dominance in the Spatial Coevolutionary Optional Prisoner's Dilemma Game

This paper studies scenarios of cyclic dominance in a coevolutionary spatial model in which game strategies and links between agents adaptively evolve over time. The Optional Prisoner’s Dilemma (OPD) game is employed. The OPD is an extended version of the traditional Prisoner’s Dilemma where players have a third option to abstain from playing the game. We adopt an agent-based simulation approac...

Evolutionary Dynamics of Cooperation under the Distributed Prisoner's Dilemma

Humans contribute to a broad range of cooperative endeavors. In many of them, the amount or effort contributed often depends on the social context of each individual. Recent evidence has shown how modern societies are grounded in complex and heterogeneous networks of exchange and cooperation, in which some individuals play radically different roles and/or interact more than others. We show that...

Epic Heroes in Ossian by Macpherson and Shahnameh by Firdausi

Nationalist sentiments characterize the Scotish James Macpherson’s Ossianic tales and the Persian Abul-Ghasim Ferdausi’s Shahnameh. Macpherson is remembered for his role in the nationalist Gaelic revival against the cultural dominance of Great Britain and Ferdausi is credited for enlivening Persian language and culture at the time of Arab dominance. However, Macpherson’s dual position, both as ...

Time and the Prisoner's Dilemma

B This paper examines the integration of computational complexity into game theoretic models. The example focused on is the Prisoner’s Dilemma, repeated for a finite length of time. We show that a minimal bound on the players’ computational ability is sufficient to enable cooperative behavior. Ill addition, a variant of the repeated Prisoner’s Dilemma game is suggested, in which players have th...
