More concepts to explore
Backward induction
Reasoning backward from terminal choices solves finite perfect-information games under appropriate preferences.
Expected utility
Expected utility evaluates uncertain outcomes using probabilities and a utility function.
Normal-form games
Players, strategies and payoff functions define a normal-form game.
Probability
A probability measure assigns nonnegative weights to events, with total weight one and countable additivity on disjoint events.
Zero-sum games and minimax
For finite two-player zero-sum games, optimal mixed strategies equalize maximin and minimax values.
