From: Quantal response equilibrium for the Prisoner’s Dilemma game in Markov strategies
The dashed line represents the Nash equilibrium. The pink circles represent the QRE curve. The orange triangles signify participants’ strategies before socialization, while the violet circles signify participants’ strategies after socialization. The QRE for PD in Markov strategies points for \(\lambda <\sim 5\) serve as a natural border between points before and after socialization.
