Abstract
We study the existence of approximate pure Nash equilibria in social context congestion games. For any given set of allowed cost functions \(\mathcal{F}\), we provide a threshold value \(\mu(\mathcal{F})\), and show that for the class of social context congestion games with cost functions from \(\mathcal{F}\), α-Nash dynamics are guaranteed to converge to α-approximate pure Nash equilibrium if and only if \(\alpha>\mu(\mathcal{F})\).
Interestingly, \(\mu(\mathcal{F})\) is related and always upper bounded by Roughgarden’s anarchy value [19].
