A further subset of the global environment often used in reinforcement learning, is what is called the Markov environment state which contains all the relevant information about the environment necessary to make an optimal decision about the future in regard to some particular goal. An approach called Nash-Q [9, 6, 8] has been proposed for learning the game structure and the agents’ strategies (to a fixed point called Nash equilibrium where no agent can We introduced Extended Markov Games as a mathematical model for multi-agent reinforcement learning, to learn policies that satisfy mul-tiple (non-Markovian) LTLspecifications in multi-agent systems. It provides a mathematical framework for modeling decision making in situations where outcomes are partly random and partly under the control of a decision maker.
