Perform a complete Alpha-Beta backup for the following game tree. Box is max, circle is min. Indicate by each node all provisional backup values, striking out old ones as they are replaced. Draw an irregular circle around groups of nodes that would not be searched because of a cutoff. Next to each irregular circle, indicate that it is an alpha cutoff or a beta cutoff. Use the Alpha-Beta Minimax algorithm that you learned in this class depth-first and the moves are searched left-to-right.
