In game theory, models are commonly classified based on several key parameters. The correct answer to your question about how game theory models are classified is:

All of these.

Explanation:

1. Number of Players: Game theory distinguishes between different games depending on how many players are involved—typically categorized as two-player games, multi-player games, cooperative games, and non-cooperative games.

2. Number of Strategies: Another classification depends on the strategies available to each player. Games can be classified as having pure strategies, mixed strategies, or a combination of both.

3. Sum of All Payoffs: Game theory considers the payoff structure, including whether the sum of the payoffs for all players remains constant (zero-sum games) or varies (non-zero-sum games).

Because all of these elements are fundamental in categorizing game theory models, the most comprehensive answer is "all of these."
