Discussion

The framework uncovers how long-memory strategies improve cooperation in social interactions, highlighting evolutionary game theory insights.

Long-memory strategies promote cooperation more effectively than short-memory strategies, providing new insights into social behavior.
Analysis reveals that the most effective strategies involve diverse informational inputs and can stabilize cooperation within populations.
The proposed framework encompasses arbitrary memory lengths and various decision rules, expanding traditional evolutionary game theory models.
The work quantifies the contribution of memory-based strategies to cooperation, offering explanations for human societal behaviors beyond conventional models.

Sun et al. (2025) studied this question.
