{wiki=Quasi-perfect_equilibrium}
Quasi-perfect equilibrium is a concept from game theory, specifically related to dynamic games and extensive form games (games represented by trees with nodes and branches indicating possible moves by players). It is an extension of the idea of subgame perfect equilibrium, which requires that players' strategies constitute a Nash equilibrium in every subgame of the original game.
