The document discusses the evolution of internal reward systems and preferences in a game with two strategies, A and B. It describes the external payoff matrix and the internal payoff matrices for two types of players. Players interact on a social network, choosing strategies that maximize their internal payoff. Occasionally, players update their type based on their neighbors' external payoff sums. The document provides an example with specific payoff matrices and discusses expectations on a k-regular graph.
