摘要:
In this article, we propose a new framework of Markov alpha-potential games to study Markov games. We show that any Markov game with finite state and finite action is a Markov alpha-potential game and establish the existence of an associated alpha-potential function. Any optimizer of an alpha-potential function is shown to be an alpha-stationary Nash equilibrium. We study two important classes of practically significant Markov games, Markov congestion games and the perturbed Markov team games, via the framework of Markov alpha-potential games, with explicit characterization of an upper bound for alpha and its relation to game parameters. In addition, we provide a semi-infinite linear programming-based formulation to obtain an upper bound for alpha for any Markov game. Furthermore, we study two equilibrium approximation algorithms, namely, the projected gradient-ascent algorithm and the sequential maximum improvement algorithm, along with their Nash regret analysis, and corroborate the results with numerical experiments.
