An Example of a Two-Player Game Player B R U(12)(0,1) Player A D(2,1)(1,0) If B plays Right then A's best reply is Down
An Example of a Two-Player Game If B plays Right then A’s best reply is Down. Player B Player A L R U D (1,2) (2,1) (0,1) (1,0)
An Example of a two-Player Game Player B R U(12)(0,1) Player A D(2,1)(1,0) So no matter what B plays, A's best reply is always Down Down is a' s dominant strategy(超优 策略)
An Example of a Two-Player Game So no matter what B plays, A’s best reply is always Down. Down is A’s dominant strategy （超优 策略）. Player B Player A L R U D (1,2) (2,1) (0,1) (1,0)
An Example of a two-Player Game Player B U(12)( R0 ,1) Player A D(2,1)(1,0) Similarly Left is B's dominant strategy
An Example of a Two-Player Game Similarly, Left is B’s dominant strategy. Player B Player A L R U D (1,2) (2,1) (0,1) (1,0)
An Example of a two-Player Game Player B R U(12)(0,1) Player A D(2,1)(1,0) Therefore, Down, Left) is dominant strategy for both players. It is the only equilibrium
An Example of a Two-Player Game Therefore, (Down, Left) is dominant strategy for both players. It is the only equilibrium. Player B Player A L R U D (1,2) (2,1) (0,1) (1,0)
