Softening and Hardening in the Iterated Prisoner’s Dilemma

This article presents two methods to evaluate and draw distinction among general cooperative aggressive strategic behavior in the iterated prisoner’s dilemma (IPD). The first method identifies classes of strategies, clusters them into subclasses based on their or disposition, then comprehensively assess behavior. second relies applying transformative manipulations that soften harden strategies a given set compare with results obtained initial set. Although examined are very different, stable convergent. While our findings agree classical analyses IPD, qualified precise. Furthermore, reproducibility prior via new experimental offer evidence. proposed comparative strategy analysis is instrument can have broad implications for analyzing games beyond dilemma.
