Environment-based preference selection promotes cooperation in spatial prisoner's dilemma games. This strategy helps cooperators form clusters, enhancing their survival against defectors, especially with environmental heterogeneity.

Area of Science:

  • Evolutionary Game Theory
  • Computational Social Science
  • Complex Systems

Background:

  • Cooperation is crucial for survival and evolutionary advantage.
  • Adopting strategies from better-performing neighbors is a key mechanism.
  • Environmental factors and individual differences influence strategy adoption.

Purpose of the Study:

  • To investigate the effect of environment-based preference selection on cooperation.
  • To explore how environmental heterogeneity influences cooperation dynamics.
  • To understand the role of adjustable preference selection parameters (α) in behavior.

Main Methods:

  • Simulations of the spatial prisoner's dilemma game.
  • Introduction of an environment-based preference selection rule.

  • Incorporation of environmental heterogeneity and an adjustable parameter α.

    • Main Results:

    • Environment-based preference selection significantly promotes cooperation.
    • Accelerated formation of cooperator clusters enhances resistance to defectors.
    • Cooperation is sustained across a wide range of parameters.

    Conclusions:

    • Environment-based preference selection is a viable strategy for promoting cooperation.
    • Environmental heterogeneity combined with preference selection is key for cooperation sustainability.
    • This mechanism offers insights into cooperation in structured populations.
