What does this research mean for the field?

In public goods games, individuals update their cooperative strategies primarily through self-adjustment based on historical payoffs rather than imitation, with an optimal self-adjustment proportion of approximately 0.9. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.CHALLENGES_CONSENSUS.

Overview

Computational modeling study demonstrates that payoff-based self-adjustment sustains cooperation over imitation in public goods games, indicating memory-driven regulation drives collective action.

Key Points

Validate empirical findings on memory-driven strategy adjustments and quantify the optimal decision parameters governing cooperation in optional public goods games.
Constructed an agent-based model on a square lattice with periodic boundary conditions incorporating prospect theory and a mixed-strategy evolutionary framework.
Systematically varied the proportion of self-adjustment, mutation rate, and sensitivity coefficient to evaluate their impact on the stationary distribution of cooperators, defectors, and loners.
Demonstrated that players update strategies primarily through payoff-based self-adjustment, relegating peer imitation to an auxiliary role.
Identified an optimal self-adjustment proportion of approximately 0.9, while lower mutation rates and reduced sensitivity coefficients maximized the emergence of stable cooperation.
