Last-iterate Convergence for Symmetric, General-sum, $2\times 2$ Games Under The Exponential Weights Dynamic

Guanghui Wang, Krishna Acharya, Lokranjan Lakshmikanthan +2

We conduct a comprehensive analysis of the discrete-time exponential-weights dynamic with a constant step size on all general-sum and symmetric $2\times 2$ normal-form games, i.e.…
