Network Games

Network Games involve interactions between players that are connected through a network structure. This type of game is prevalent in various fields such as economics, computer science, and social sciences. Understanding key terms and vocabulary in network games is crucial for analyzing and optimizing strategies in these games.

Network Structure refers to the arrangement of connections between players in a network game. This structure can be represented as a graph, where nodes represent players, and edges represent connections or interactions between players. The network structure plays a significant role in determining the strategies and outcomes of network games.

Player is an individual or entity participating in a network game. Players make decisions based on their objectives and the actions of other players in the game. Each player aims to optimize their utility or payoff based on the network structure and game rules.

Strategy is a plan of action chosen by a player to achieve their objectives in a network game. Players select strategies based on their knowledge of the network structure, the actions of other players, and the potential outcomes of the game. Strategies can be simple or complex, depending on the complexity of the network game.

Payoff is the outcome or result that a player receives based on their chosen strategy and the strategies of other players in a network game. Payoffs can be positive or negative, representing gains or losses for a player. Players aim to maximize their payoffs by selecting optimal strategies in network games.

Equilibrium is a state in a network game where no player has an incentive to change their strategy unilaterally. In equilibrium, each player's strategy is optimal given the strategies of other players. There are different types of equilibria in network games, such as Nash equilibrium and correlated equilibrium, which describe stable outcomes in the game.

Nash Equilibrium is a concept in game theory where each player's strategy is optimal given the strategies of other players. In a Nash equilibrium, no player can unilaterally deviate from their strategy to improve their payoff. Nash equilibrium is a fundamental concept in analyzing network games and predicting player behavior.

Correlated Equilibrium is a solution concept in game theory where players coordinate their strategies based on external signals or communication. In a correlated equilibrium, players follow a joint probability distribution over strategies, ensuring that no player has an incentive to deviate from the correlated strategy. Correlated equilibrium allows for coordination among players in network games.

Network Formation Game is a type of game where players not only choose their strategies but also decide on the connections or links between them. In a network formation game, players aim to maximize their payoff by strategically forming connections with other players. The network structure evolves based on the decisions of players in the game.

In a congestion game, players aim to minimize their travel time or cost by selecting paths that are less congested. Congestion games are common in transportation networks, communication networks, and resource allocation problems.

Price of Anarchy is a measure of the inefficiency in a network game due to selfish behavior of players. The price of anarchy quantifies the ratio between the social welfare in a Nash equilibrium and the socially optimal outcome in a network game. A high price of anarchy indicates a significant loss of efficiency due to selfish behavior of players in the game.

Algorithmic Game Theory is a field that combines game theory and computer science to study the computational aspects of strategic interactions.
