Extensive form

The extensive form is a way of representing a game or decision process that shows all possible moves, choices, and outcomes step-by-step. It uses a tree-like diagram where each branch represents a decision or chance event, and each node shows what options are available at that point. This format helps analyze strategic interactions over time, considering how players might react to each other's moves. It's useful for understanding complex scenarios, such as negotiations or competitions, by visually mapping out possible sequences and consequences in a structured way.
