Definition:Model of Rational Choice

Definition
A model of rational choice for a player in a game consists of:
 * $(1): \quad$ A set $A$ of moves from which the player may choose


 * $(2): \quad$ A set $C$ of consequences of each of those moves


 * $(3): \quad$ A consequence function $g: A \to C$ which maps a consequence to each action


 * $(4): \quad$ A preference relation $\succsim$, which is a total ordering on $C$.
