What is game theory in simple terms?
Game theory is the study of how and why people make decisions. (Specifically, it is “the study of mathematical models of conflict and cooperation between intelligent rational decision-makers”.) It helps people understand parts of science and politics.

What is game theory John Nash?

There does not always exist a pure Nash equilibrium. Theorem 1 (Nash, 1951) There exists a mixed Nash equilibrium. … for every i, hence must have pi(s, α) ≤ 0 for every i and every s ∈ Si, hence must be a Nash equilibrium. This concludes the proof of the existence of a Nash equilibrium.
How do you find equilibrium in game theory?
To find the Nash equilibria, we examine each action profile in turn. Neither player can increase her payoff by choosing an action different from her current one. Thus this action profile is a Nash equilibrium. By choosing A rather than I, player 1 obtains a payoff of 1 rather than 0, given player 2’s action.

Which is the unrealistic of game theory?
Firstly, game theory assumes that each firm has knowledge of the strategies of the other as against its own strategies and is able to construct the pay-off matrix for a possible solution. This is a highly unrealistic assumption and has little practicability.
