Introduction to Game Theory

Game theory is a branch of mathematics that studies strategic decision making. It is used to analyze how people and groups interact with each other and make decisions in various situations.

What is a Game?

A game is an interactive situation where two or more players compete for resources or rewards. The players must use their knowledge and skills to make the best decisions and maximize their own rewards.

Types of Games

There are two main types of games: zero-sum games and non-zero-sum games.

In a zero-sum game, one player's gain is equal to another player's loss. This means that the total rewards of all players in the game add up to zero. Examples of zero-sum games include chess and poker.

In a non-zero-sum game, the total rewards of all players in the game do not add up to zero. This means that the rewards of one player do not necessarily have to be equal to the losses of another player. Examples of non-zero-sum games include rock-paper-scissors and the Prisoner's Dilemma.

Strategies

Players in a game must use strategies to maximize their rewards. A strategy is a plan of action that a player will use to achieve their goals.

Players can use different strategies depending on the game they are playing. Some strategies are more successful than others, and the best strategies often depend on the type of game and the players involved.

Practice Problems

1. In a game of rock-paper-scissors, what is the best strategy for a player to use?

Answer: The best strategy for a player to use in a game of rock-paper-scissors is to use a mixed strategy. A mixed strategy involves randomly choosing between rock, paper, and scissors, so that the opponent cannot predict what move the player will make.

1. In a game of chess, what is the best strategy for a player to use?

Answer: The best strategy for a player to use in a game of chess is to use a combination of opening, mid-game, and endgame strategies. Opening strategies involve controlling the center of the board and developing pieces quickly. Mid-game strategies involve attacking the opponent's pieces and controlling key squares. Endgame strategies involve promoting pawns, trading pieces, and setting up checkmates.
