What is meant by a Subgame Perfect Nash equilibrium?
A Subgame Perfect Nash Equilibrium (SPNE) is a concept in game theory that refines the traditional Nash equilibrium by incorporating the idea of subgames. In the context of dynamic or sequential games, a game can be divided into subgames, each representing a stage or phase of the overall game.
