Cooperation enhanced by inhomogeneous activity of teaching for evolutionary Prisoner's Dilemma gamesSzolnoki, Attila ; Szabó, György, 1950-Evolutionary Prisoner's Dilemma games with quenched inhomogeneities in the spatial dynamical rules are considered. The players following one of the two pure strategies (cooperation or defection) are ... distributed on a two-dimensional lattice. The rate of strategy adoption from randomly chosen neighbors is controlled by the payoff difference and a two-value pre-factor w characterizing the players whom the strategy learned from. The reduced teaching activity of players is distributed randomly with concentrations ? at the beginning and fixed further on. Numerical and analytical calculations are performed to study the concentration of cooperators as a function of w and ? for different noise levels and connectivity structures. Significant increase of cooperation is found within a wide range of parameters for this dynamics. The results highlight the importance of asymmetry characterizing the exchange of master-follower role during the strategy adoptions.Source: Europhysics letters : EPL. - ISSN 0295-5075 (Vol. 77, no. 3, 2007, str. 30004-p1-30004-p5)Type of material - article, component part ; adult, seriousPublish date - 2007Language - englishCOBISS.SI-ID - 1024043612
