The Dynamics of Policy Gradient in Social Dilemmas with Partner Selection
Analytical derivation of policy-gradient dynamics with partner selection proves population variance is necessary for cooperation emergence and identifies a sufficient condition for cooperation-promoting populations via a stochastic Wiener process model.
