Motion of influential players can support cooperation in Prisoner’s Dilemma

چکیده
We study a spatial Prisoner’s dilemma game with two types (A and B) of players located on a square lattice. Players following either cooperator or defector strategies play Prisoner’s Dilemma games with their 24 nearest neighbors. The players are allowed to adopt one of their neighbor’s strategy with a probability dependent on the payoff difference and type of the given neighbor. Players A and B have different efficiency in the transfer of their own strategies; therefore the strategy adoption probability is reduced by a multiplicative factor (w < 1) from the players of type B. We report that the motion of the influential payers (type A) can improve remarkably the maintenance of cooperation even for their low

Impact of density and interconnectedness of influential players on social welfare
We show that in defection prone environments influential players must be rare and weakly interconnected to optimally promote cooperation in the prisoner’s dilemma game. Conversely, low temptations to defect warrant a high level of social welfare even if influential players are common, yet still demand the latter be weakly interconnected for cooperation to thrive. 2014 Elsevier Inc.

متن کاملPrisoner’s Dilemma in One-dimensional Cellular Automata: Visualization of Evolutionary Patterns
The spatial Prisoner’s Dilemma is a prototype model to show the emergence of cooperation in very competitive environments. It considers players, at site of lattices, that can either cooperate or defect when playing the Prisoner’s Dilemma with other z players. This model presents a rich phase diagram. Here we consider players in cells of one-dimensional cellular automata. Each player interacts w...
متن کاملMaking new connections towards cooperation in the prisoner's dilemma game
Evolution of cooperation in the prisoner’s dilemma game is studied where initially all players are linked via a regular graph, having four neighbors each. Simultaneously with the strategy evolution, players are allowed to make new connections and thus permanently extend their neighborhoods, provided they have been successful in passing their strategy to the opponents. We show that this simple c...
متن کاملGames With Tolerant Players
A notion of π-tolerant equilibrium is defined that takes into account that players have some tolerance regarding payoffs in a game. This solution concept generalizes Nash and refines ε-Nash equilibrium in a natural way. We show that π-tolerant equilibrium can explain cooperation in social dilemmas such as Prisoner’s Dilemma and the Public Good game. We then examine the structure of particularly...
متن کاملModeling Cooperation between Nodes in Wireless Networks by APD Game
Cooperation is the foundation of many protocols in wireless networks. Without cooperation, the performance of a network significantly decreases. Hence, all nodes in traditional networks are required to cooperate with each other. In this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whe...
