Question
(In this and all other questions in which a game matrix is given, Player 1 chooses the row, Player 2 chooses the column, and if there is a Player 3, she chooses the matrix.)
Which is true for the following game according to the solution concept of iterated elimination of strongly dominated strategies?
A B C
a 1,4 -2,-2 4,0 b 6,2 -2,3 3,-6 c 5,-1 -1,0 5,2 d 0,0 0,3 5,4
The unique strategy profile that solves the game is (b,A).
The strategy profiles (c,C) and (d,C) solve the game.
None of the other alternatives is true.
The unique strategy profile that solves the game is (d,C).
Player 2 is guaranteed a payoff of 4.
Player 1 is guaranteed a payoff of 6.
Solution
To solve this game using the concept of iterated elimination of strongly dominated strategies, we need to identify and eliminate strategies that are always worse than another strategy, regardless of what the other player does.
Let's start with Player 1:
- Comparing strategy 'a' with 'b', 'b' is not always better than 'a'. So, we can't eliminate any of them.
- Comparing strategy 'a' with 'c', 'c' is not always better than 'a'. So, we can't eliminate any of them.
- Comparing strategy 'a' with 'd', 'd' is not always better than 'a'. So, we can't eliminate any of them.
- Comparing strategy 'b' with 'c', 'c' is not always better than 'b'. So, we can't eliminate any of them.
- Comparing strategy 'b' with 'd', 'd' is not always better than 'b'. So, we can't eliminate any of them.
- Comparing strategy 'c' with 'd', 'd' is not always better than 'c'. So, we can't eliminate any of them.
Now, let's move to Player 2:
- Comparing strategy 'A' with 'B', 'A' is not always better than 'B'. So, we can't eliminate any of them.
- Comparing strategy 'A' with 'C', 'A' is not always better than 'C'. So, we can't eliminate any of them.
- Comparing strategy 'B' with 'C', 'B' is not always better than 'C'. So, we can't eliminate any of them.
So, we can't eliminate any strategy for both players. Therefore, the statement "None of the other alternatives is true." is correct.
