Payoff Function
The payoff function in a stochastic game assigns a numerical reward (or cost) to each player based on the current state of the game and the actions taken by the players.
State Space
The state space in a stochastic game is the set of all possible configurations or situations the game can be in at any step.
Discount Factor
The discount factor is a value between 0 and 1 that determines the present value of future payoffs, reflecting the concept of time preference in a stochastic game.
Nash Equilibrium in Stochastic Games
A Nash equilibrium in a stochastic game is a strategy profile where no player has an incentive to unilaterally deviate, considering the probabilistic nature of the game and the strategies of the other players.
Stochastic Game Definition
A stochastic game is a dynamic game with probabilistic transitions between states, played by one or more players, where the transition probabilities are often affected by the players' actions.
Transition Probabilities
Transition probabilities in a stochastic game are the likelihoods of moving from one state to another, given a particular set of actions by the players.
Action Space
The action space is the set of all actions that players can take. In a stochastic game, these actions can influence the transition probabilities between states.
