Evolutionary dynamics in spatial threshold public goods game with the asymmetric return rate mechanism

摘要: Abstract In reality, cooperators often are provided a higher return rate for their contributions. Inspired by the this paper introduces asymmetric mechanism, where is between and defectors. This mainly studies how mechanism influences evolutionary dynamics in spatial threshold public goods game on two different complex networks, namely square lattice Barabasi-Albert scale-free network. The simulation results show that increasing sensitivity spread of cooperation more effective than defection not only to promote cooperation, but also elevate provision goods. addition, moderate value best both promotion
