For the past year, I’ve been working in my spare time through a very interesting paper by Kleshnina et al. (2023). The paper concerns an evolutionary game theory model where individuals play an iterated Prisoner’s Dilemma with an environmental feedback. In a previous post, I experimented with a method to automate the identification of the subgame-perfect Nash equilibria and their parameter-value…
