What is the concept of backward induction?

The concept of backward induction is a solution concept used in game theory to determine the optimal strategy for a sequential game. It involves working backwards from the final stage of the game to determine the best course of action at each previous stage. By considering the possible outcomes and payoffs at each stage, players can make rational decisions that maximize their expected utility. Backward induction is particularly useful in games with a finite number of stages and perfect information.
