Game Theory - Introduction

Max Euwe, 1935 Chess World Champion: Strategy requires thought; Tactics require observation.

studies situations in which , and also possibly , to influence the outcome of the parties' interaction to each party's advantage. The situation involves between the participants — called — because at the expense of the other players. What each player obtains from a particular outcome is called the . Each player can choose among a number of actions to influence his pay-off. However, each player's pay-off depends on the other players' choices. Moreover, outcomes can also be influenced by (see the Wikipedia's introduction to .)

The between the two players in a zero-sum game resemble between enemy states. Players make moves and counter-moves, until the declare the game is ended. The rules of engagement determine what each player can or must do at each stage ( ) as the game unfolds. For example, in the game both players simultaneously make one move, with rock beating scissors beating paper beating rock. While this game consists of only one move, games like require many moves to resolve the conflict.

Thus, a player's strategy provides him with a move depending on what the other player has done, and/or chance events, as the game unfolds. Different moves and/or means to choose the move in a given situation are . A game with a finite number of stages and a finite number of moves at each stage is called a A finite game has a finite number of distinct strategies available to each player. The game of chess is a finite game, despite its complexity and vast number of strategies.

The choice of a particular strategy by each player determines the pay-off to each player.

The following illustrates the concepts introduced above.

Colonel Blotto must defend two cities with one indivisible regiment of soldiers. His enemy, Colonel Sotto, plans to attack one city with his indivisible regiment. City I has a value of 10 units, while City II has a value of 5 units. If Colonel Sotto attacks a defended city, Sotto loses the battle and obtains nothing. If Colonel Sotto attacks an undefended city, he obtains the value of the city, while Colonel Blotto loses the value of the city. Neither Colonel knows what the other plans to do.

Normal Form.

Colonel Sotto has two "pure strategies," Attack City I and Attack City II; Colonel Blotto has two "pure strategies," Defend City I and Defend City II. Each Colonel weighs each pure strategy against his enemy's pure strategies.

Examining his options, Colonel Sotto thinks, "Blotto might defend City I, since City I is worth more than City II. Why don't I attack City II"? Conversely, Colonel Blotto thinks, "Sotto might attack City II, since he thinks I will defend City I. Why don't I defend City II"? Thinking further into the game, Sotto thinks, "If Blotto is trying to read my mind, he might defend City II. Maybe I should attack City I after all."

Each Colonel's attempt to read his enemy's mind degenerates into an infinite regression .

However, a solution concept lurks in the Colonels' "gedank" experiments . Sotto attacks each city with positive probability, while Blotto defends each city with positive probability. Furthermore, since City I is worth twice as much as City II, the probability that Blotto defends City I should be twice as great as the probability that he defends City II. Conversely, since Sotto loses in a head-to-head confrontation with Blotto, the probability that Sotto attacks City II should be twice as great as the probability that he attacks City I. Both probabilities for each Colonel must add-up to one. Therefore, the optimal strategy for Colonel Blotto is to defend City I with probability 2/3, and to defend City II with probability 1/3. In the meantime, the optimal strategy for Colonel Sotto is to attack City I with probability 1/3, and to attack City II with probability 2/3.

Strategies consisting of probability weighted pure strategies are called mixed strategies.

If Colonel Sotto plays the mixed strategy (Attack City I, Attack City II) = (1/3, 2/3), he expects to gain:

0 * 1/3 + 5 * 2/3 = 3 1/3 units if Blotto plays Defend City I, 10 * 1/3 + 0 * 2/3 = 3 1/3 units if Blotto plays Defend City II.

If Colonel Blotto plays the mixed strategy (Defend City I, Defend City II) = (2/3, 1/3), he expects to lose:

0 * 2/3 + 10 * 1/3 = 3 1/3 units if Sotto plays Attack City I, 5 * 1/3 + 0 * 2/3 = 3 1/3 units if Sotto plays Attack City II.

Colonel Sotto's strategy assures him of an expected gain of at least 3 1/3 units; Colonel Blotto's strategy assures him of an expected loss of not more than 3 1/3 units. The value of the game is 3 1/3 units.

Extensive Form.

The next diagram shows the extensive form, or game tree , for the Colonel Blotto Game. The blue circle represents Colonel Sotto's decision node, while the red circles represent Colonel Blotto's decision nodes. Colonel Blotto's decision nodes are contained in the yellow ellipse, because Blotto does not know which node he actually is in, since Blotto and Sotto choose their strategies simultaneously. The numbers at the green nodes are the pay-offs to (Sotto, Blotto) with the strategies chosen.

The yellow ellipse is called the information set for Colonel Blotto, since Blotto just knows that he is at one or the other node in the ellipse.

The game is symmetrical in the sense that I can start the game tree with Colonel Blotto's decision node instead.

"Doc" Holliday's Revenge

On October 26, 1881, the bad blood between the Earps, Clantons, and McLaurys came to a head at the OK Corral . Billy Clanton, Frank McLaury, and Tom McLaury were killed. Doc Holliday, Virgil and Morgan Earp were injured. Miraculously, Wyatt Earp was unharmed, while the unarmed Isaac "Ike" Clanton survived by running away. Many people believed that Doc Holliday shot-gunned an unarmed Tom McLaury in the back as he was attempting to flee the scene.

Ike Clanton and his friends and associates, known as the "cowboys," swore to get their revenge on the Earps and Holliday. In the ensuing months, Morgan Earp was murdered and Virgil Earp seriously wounded in an ambush. A few days later, Wyatt Earp apparently shot and killed Frank Stillwell, a Clanton associate, and another man believed involved in the ambush. Over the next few years, many more of the "cowboys" were killed.

Although close to death from tuberculosis, in 1887 Doc Holliday decides to look up Ike Clanton and to settle their differences once and for all. On June 1, 1887, Doc Holliday and J.V. Brighton corner Ike Clanton near Springerville, Arizona. Doc tells J.V. to stay out of it for the time being.

Ike and Doc have each a pistol and shotgun. Ike and Doc, spurnning their pistols in favour of their shotguns, press forward towards each other. At long range , Ike — with his cowboy background — is a better shot than Doc. At middle range , Doc — the seasoned gunfighter — out-guns Ike. Both desperadoes are deadly at close range . The probabilities that either rogue will kill the other with a blast from his single-shot shotgun appear in the following table:

The pay-off to Doc is 10 units if Doc survives and Ike is killed, -10 units if Doc is killed and Ike survives. Doc and Ike's strategies are:

Normal Form.

Always the consummate gambler, Doc Holliday correctly computes his pay-off matrix as:

Furthermore, Doc realizes that strategy D M dominates strategies D L and D C , in that his expected pay-off is higher with D M no matter what Ike does. If Ike is rational enough — if Ike correctly computes his pay-off matrix as the negative of Doc's pay-off matrix — Ike will choose strategy I L , because I L dominates strategies I M and I C provided Doc chooses strategy D M .

The pair of pure strategies, the dominant strategies (D M , I L ), is the "solution" to the game. The value of the game is 0, the pay-off when Doc chooses strategy D M and Ike chooses I L .

The pair of strategies, (D M , I L ), determines a saddle point of the pay-off matrix. Notice that the pay-off matrix entry, "0," is the largest entry in the I L column and the smallest entry in the D M row. A strategy pair whose pay-off matrix entry is a saddle point is called an equilibrium strategy pair .

The next diagram shows the extensive form, or game tree , for Doc Holliday's Game. The blue circle represents Doc Holliday's decision node, while the red circles represent Ike Clanton's decision nodes. Ike Clanton's decision nodes are contained in the yellow ellipse, because Ike does not know which node he actually is in, since Ike and Doc choose their strategies simultaneously. The numbers at the green nodes are the pay-offs to (Doc, Ike) with the strategies chosen.

The yellow ellipse is called the information set for Ike Clanton, since Ike just knows that he is at one of the three nodes in the ellipse.

The game is symmetrical in the sense that I can start the game tree with Ike Clanton's decision node instead.

Doc Holliday survived the show-down, apparently dying from tuberculosis on November 8, 1887 in Colorado. Not so funny, after all.

Graphical Solution of a 2 x n or m x 2 Game

A two-person zero-sum game with a pay-off matrix with dimensions either 2 x n, or m x 2 can be solved graphically. For example, consider the game with the 2 by 4 pay-off matrix:

Since this matrix does not have a saddle point, one must resort to mixed strategies for a solution. If Player I plays strategy I 1 with probability ß , and strategy I 2 with probability (1 - ß) his expected returns, R, against each of Player II's strategies are:

Player I's expected return against a particular strategy of Player II is a function of ß, a straight line . The next diagram graphs these straight-line functions as ß varies from 0 to 1 . The probability ß is graphed along the x-axis, while Player I's return R i against Player II's ith strategy is graphed along the y-axis.

Player I's "Optimal" Strategy.

If Player I sets ß = .4, Player I can expect at least a return R = 1.6 against any strategy or combination of strategies that Player II chooses to play. The (ß, R) = (0.4, 1.6) point occurs at the intersection of the R 1 and R 3 lines.

Player II's "Optimal" Strategy.

Since Player's I's mixed strategy (0.4, 0.6) assures him of an expected gain of 1.6 units, Player II wants a strategy that will limit his expected loss to 1.6 units . Moreover, Player II can restrict his choice of strategies to II 1 and II 3 , because the diagram shows that strategies II 2 and II 4 expose him to losses greater than 1.6 units.

If Player II plays strategy II 1 with probability µ , and strategy II 3 with probability (1 - µ) his expected losses L against Player I's mixed strategies are:

If Player II sets µ = 1 / 5 = .2 , his expected losses are:

Since Player II can limit his losses independently of Player I's choice of mixed strategy, Player II's mixed strategy (0.2, 0, 0.8, 0) guarantees him of an expected loss of no greater than L = 1.6.

Game Solution.

Player I plays a mixed stragey of   (0.4, 0.6)   and Player II plays a mixed strategy of   (0.2, 0, 0.8, 0).  The value of the game is 1.6 units.

The Min-Max Theorem for Matrix Games

A matrix game can be described by its pay-off matrix, an m by n matrix A  =  [a i, j ], the set X of all probability distributions x on the integers {1, 2, . . . , m}, and the set Y of all probability distributions y on the intergers {1, 2, . . . , n}. Thus

If Player I selects a probability distribution x and Player II selects a probability distribution y , the pay-off to Player I is P( x , y ) while the pay-off to Player II is -P( x , y ), where:

ie, the expected pay-off equals the product of the row vector x T and the matrix A, (another row vector), and the column vector y

Lower Value: Max-Min Game.

P( x , y 0 ) = min y in Y P( x , y )

Therefore, Player I should choose x 0 in X so that:

v I = min y in Y P( x 0 , y ) = max x in X [ min y in Y P( x , y ) ]

The number v I is called the lower value, or the maxmin value, of the game.

Upper Value: Min-Max Game.

P( x 0 , y ) = max x in X P( x , y )

Therefore, Player II should choose y 0 in Y so that:

v II = max x in X P( x , y 0 ) = min y in Y [ max x in X P( x , y ) ]

The number v II is called the upper value, or the minmax value, of the game.

Min-Max Theorem for Matrix Games.

If x 0 and y 0 are the strategies chosen as indicated above, then:

v I = v II = v = the value of the game = P( x 0 , y 0 )

If x is any mixed strategy in X, and y is any mixed strategy in Y, then:

P( x , y 0 ) x 0 , y 0 ) x 0 , y )

Thus the strategy pair ( x 0 , y 0 ) is the solution to the game. The two strategies provide a saddle point in mixed strategies in the Cartesian product domain of X x Y.

Linear Programming Solution for Matrix Games

One can conveniently illlustrate the method used to turn a matrix game into a linear programming problem with an example (Hadley, 427). Suppose that player I has 3 strategies, player II has 5 strategies, and the payoff matrix A is given by:

P l a y e r I

P l a y e r   II

3 5 0 9 6 2 6 8 1 2 1 7 4 9 3 If player I plays strategy 2, his payoff depends on which strategy player II has chosen to play. If player II knows player I is playing strategy 2, she should play her 4th strategy, because then she only pays him 1 unit. But if player I plays strategy 1 instead, she must pay him 9 units. I assume that players know the payoff matrix A, but that players 'announce' their strategies simultaneously. Player I wants to maximize the payoff; player II wants to minimize the payoff. The Min-Max Theorem suggests each player determine the choice of strategies on the basis of a probability distribution over the player's list of strategies. That is, player I chooses row 1, 2, or 3 with probabilities x 1 , x 2 ,and x 3 . Player II chooses the columns with probabilities y 1 , y 2 , y 3 , y 4 , and y 5 . Note that the x's and y's must be non-negative and each set must add to one. To turn this into a linear programming problem write: Primal Linear Program Maximize P = x , with x nonnegative 3*x + 2*x + 1*x - 1*x >= 0 5*x + 6*x + 7*x - 1*x >= 0 0*x + 8*x + 4*x - 1*x >= 0 9*x + 1*x + 9*x - 1*x >= 0 6*x + 2*x + 3*x - 1*x >= 0 1*x + 1*x + 1*x + 0*x = 1 where the extra variable, x 4 , is the expected payoff (the value) of the game. The equation, Maximize P = x 4 , with x 4 nonnegative, is the objective function. Player I wants to maximize the objective function, the expected payoff. Then there is an equation for each column of A. Why? If player II plays her 1st strategy, the expected payoff to player I is: 3*x 1 + 2*x 2 + 1*x 3 . If player I choses his probability distribution optimally, his expected payoff should be greater than or equal x 4 , the expected value of the game. This argument applies to each of A's columns. The dual linear program to the primal linear program is: Dual Linear Program Minimize D = y , with y nonnegative 3*y + 5*y + 0*y + 9*y + 6*y - 1*y 2*y + 6*y + 8*y + 1*y + 2*y - 1*y 1*y + 7*y + 4*y + 9*y + 3*y - 1*y 1*y + 1*y + 1*y + 1*y + 1*y + 0*y = 1 Minimize D = y 6 , with y 6 nonnegative, is the objective function. Player II wants to minimize the objective function, the expected payoff. Then there is an equation for each row of A. Why? If player I plays his 1st strategy, the expected payoff to player II is: 3*y 1 + 5*y 2 + 0*y 3 + 9*y 4 + 6*y 5 . If player II choses her probability distribution optimally, her expected payoff should be less than or equal y 6 , the expected value of the game. This argument applies to each of A's rows. If one solves this linear programming problem using one of the available methods, the optimal progams: x T = (x 1 , x 2 , x 3 ) = (0.667, 0.333, 0) and y T = (y 1 , y 2 , y 3 , y 4 , y 5 ) = (0.889, 0, 0.111, 0, 0), are the Max-Min and Min-Max solutions, while the value, x 4 = y 6 = 2.667, is the value of the matrix game. Value of the Game - Nonnegative. To ensure that the value of an arbitrary matrix game is nonnegative when using linear programming to find its solution, add the absolute value of the most negative entry of the pay-off matrix to each entry of the pay-off matrix. After solving the modified game, subtract this constant from its value to get the value of the original matrix game. You can play this matrix game using the form below. You are the row player, Player I. Use the bonus random number to select the row you want to play. Can you can beat the value of the game over a sequence of games? Click the row you want to play. The program selects a column using its optimal strategy. It ignores the row you choose.     y y y y y Create and play your own matrix game!

Suppose Player I plays his optimal strategy , x T = (x 1 , x 2 , x 3 ) = (0.667, 0.333, 0), and Player II plays one of her pure strategies. The vector x T * A shows the amount Player II can expect to pay to Player I for each pure strategy she plays. * A = (2/3, 1/3, 0) * 3 5 0 9 6 2 6 8 1 2 1 7 4 9 3 Notice that only pure strategies 1 and 3 ensure Player II of paying the minimum of 2.6667 units, when Player I plays his optimal mixed strategy. Likewise, the vector A * y shows the amount Player I can expect to receive from Player II for each pure strategy he plays against her optimal strategy. A * = 3 5 0 9 6 2 6 8 1 2 1 7 4 9 3 Notice that only pure strategies 1 and 2 ensure Player I of receiving the maximum of 2.6667 units, when Player II plays her optimal mixed strategy. Worthwhile Strategies. Pure strategies that appear in an optimal strategy with positive probability are called worthwhile strategies (Thomas, 37). Set of Optimal Mixed Strategies. For each player in a two-person zero-sum matrix game, the set of optimal mixed strategies is a closed, convex set (Karlin, 36). For each player, the optimal strategy calculated from the equivalent linear programming problem is an extreme point of the player's set of optimal strategies. This follows because in a linear programming problem, an optimal program obtains at a vertex of the feasible set, and the feasible set must contain the set of optimal strategies. Pure Strategy as a Mixed Strategy. A pure strategy is a mixed strategy with the component corresponding to the probability of playing the pure strategy equal to 1. The Snow-Shapley Theorem for Matrix Games. Consider again the two-person zero-sum game with pay-off matrix: A = 3 5 0 9 6 2 6 8 1 2 1 7 4 9 3 This game has optimal mixed strategies: If one strikes out the rows and columns of A corresponding to strategies played with zero probability, one gets the reduced matrix M corresponding to the reduced matrix game with pay-off matrix M: M = 3 0 2 8 This procedure of striking out "worthless strategies" produces a matrix M whose inverse M (-1) exists: M =  0.3333 0 -0.0833 0.1250 Furthermore, letting e T = (1, 1), ie the vector whose components are all one, the value of the game, v, is given by: v = e T * M (-1) * e = 2.6667. Moreover, the optimal strategies for Player I and Player II in the reduced game are: x 0 = v * e T * M (-1) = (0.6667, 0.3333), and y 0 = v * M (-1) * e = (0.8889, 0.1111).          Finally, the value of the original game is also v, and the optimal strategies for Player I and Player II in the original game are obtained by setting to zero the probability of playing a worthless strategy. Snow-Shapley Theorem. Consider any two-person zero-sum matrix game with pay-off matrix A. If x is an extreme point of X 0 , Player I's set of optimal strategies, and if y is an extreme point of Y 0 , Player II's set of optimal strategies, there exists a square, nonsingular submatrix M of A such that: v = e T * M (-1) * e , x 0 = v * e T * M (-1) , y 0 = v * M (-1) * e , where e is the vector of the same dimension as M all of whose components equal 1, v is the value of the game, and x 0 and y 0 correspond to the non-zero components of x and y , respectively.

Research in LIDS focuses on efficient and scalable algorithms for large scale problems, their theoretical understanding, and the deployment of modern optimization techniques to challenging settings in diverse applications ranging from communication networks and power systems to machine learning. In addition, there is a natural overlap between optimization and control, as much of modern control theory rests on optimization formulations. Finally the increased interest in systems that involve simultaneous optimization by several, possibly competing agents has led to several research thrusts that rely on game-theoretic approaches.

Operations Research A two-person game has two players.A game in which one player wins what the other player loses is called a zero-sum game. The theory of two-person zero-sum games is the foundation of more complicated games, such as games with more than two players (n-person games), and games in which the players can benefit through cooperation, with or without collusion, side payments, or binding agreements.
