- A normal form game has a set of players. Each player has a set of strategies. These players each select a strategy and play their selections simultaneously. In this manner, no player is responding to another's selection. Furthermore, we think of the players' strategies as setting the rules of the game.

In game theory, normal form is a description of a game. Unlike extensive form, normal-form representations are not graphical per se, but rather represent the game by way of a matrix.
Utility of Agents. Utility function u(!i) is a mapping from the state of the world to a real number. Utility function quanti es agent's preferences over the states of the world. If !1 !2, then u(!1) u(!2).
We represent the normal form game using the following matrix known as a payo matrix. Player 1’s strategies are on the left-side while Player 2’s strategies are on the top of the matrix. Each cell represents the payo s of the form (u 1(s 1;s 2);u 2(s 1;s 2)) for the selected strategies s 1 2S 1 and s 2 2S 2. Player 2 Quiet Fink Player 1 ...

Identify situations in which normal form games are a suitable model of a problem. Manually calculate the best responses and Nash equilibria for two-player normal form games. Compare and contrast pure strategies and mixed strategies.
Definition 1 (Normal form game). A normal form game G = D N;(S j) j2N;(u j) j2N E consists of: 2In fact, mixed strategies in game theory provided one of the motivations for von Neumann and Morgenstern’s work on their representation
1 Normal Form Games. normal form Game G consists of three elements G = (I, S, u); where. I = {1, 2, . . . , n} is the set of decision makers, the players. S = S1, ×S2 × · · · × Sn describes the feasible actions of the players. The players choose a strategy. = (s1, s2, . . . , sn) ∈ S simultaneously. An outcome is obtained.
