In economics and #Game Theory, complete information is an economic situation or a game where the information about the market participants or players are readily available to all participants.
While in #Game Theory, a sequential game is considered perfect information (not to be confused with Complete information) if each player are perfectly informed of all the events that have occurred or is occuring, e.g. chess.
Dynamic programming uses backward induction as a main method for solving the Bellman equation. In #game theory, backward induction is mainly used to compute subgame perfect equilibira in sequential game.
