Question
Consider a game between player A with a choice between moves d₁ and d₂, and player B with a choice between
81 and 82, and the pay-offs given by:
3₁
Consider a zero-sum game with the following payoff matrix for player 1:
61 62
d₁ (4,6) (7,2)
d₂ (2,8) (5,4)
Is that game separable?
a. Separable with
r₁(d₁) = 5, r₁(d₂) = 2, 72(81) = 1, 72(82) = 4, (s₁ (d₁) = 2, 8₁ (d₂) = 4,82 (81) = 4, 82 (82) = 0
b. Separable with a different solution that the ones proposed
c.
Separable with
r₁(d₁) = 3, r1(d₂) = 3,(61) = 0, 72(82) = 1, (81 (d₁) = 1, 81 (d₂) = 4, 82 (81) = 5, 82 (82) = 2
No, not separable.
d.
e.
Separable with
ri (d₁) = 4, r₁(d₂) = 1, r2(81) = -1, 72(82) = 2, (81 (d₁) = 1, 81 (d₂) = 4, 82 (81) = 6, 82 (8₂) = 1
f. Separable with
r₁(d₁) = 4, r₁(d₂) = 2, 7₂(81) = 0,72(8₂) = 3, (s₁ (d₁) = 1, 8₁ (d₂) = 3, 82 (81) = 5, 82 (8₂) = 1
Consider the payoff matrix M for a zero-sum game as defined below:
81 82
d₁0-2
d₂-2-1
M1 M₂ M3 M4 M5
d₁ 0 1 5 6 8
d₂ 10 6
5
2 3
O a. r* = (1/2, 1/2), y* = (1/2, 1/2), V =0
O b. r* = (0, 1), y* = (1/2, 1/2), [V| = 1/2
O c. x =

O d. x* =
(2/3, 1/3), y* = (2/3, 1/3), |V| = 4/3
O e. r* = (1/3, 2/3), y* = (2/3, 1/3), |V| = 1/3
O f. * = (1/3,2/3), y* = (1/3,2/3), [V| = 4/3
O g. x* = (2/3, 1/3), y* = (1/3,2/3), [V| = 1/3
Oh.
Another answer
Player 1 will play d₁ with probability
The two moves Player 2 needs to considering playing the most are
probabilities
and
The value of the game is
, and do with probability
The payoffs relate to player 1 who must choose between moves d₁ and d2, while player 2 has potential moves
ans 82.
Find the optimal strategies x* and y* for players 1 and respectively. What is the value V of the game?
and
+
with respective
Note: you need to enter probabilities as numerical answers to 3 decimal places, not fractions. For example, if oneanswer
is 1/3, type 0.333. Also, for Player 2, make sure to mention to first mention their most likely move.
