Question 10

+1 markWritten answer

GAMES: ALPHA-BETA Consider a game tree with the root node as MAX, where an arbitrary path from the root reaches the subtree shown in the figure.

Each leaf node A to D takes a UNIQUE EVAL VALUE from the set {1, 2, 3, 4}. Alpha-Beta algorithm is entering the subtree with alpha=1 and beta=3; find an optimal eval assignment (for nodes A to D) that maximizes the number of leaves pruned; find the minimax value, the type of cuts and the leaves pruned for that assignment. Based on the above data, answer the given subquestions.

Enter the label of leaf nodes pruned by Alpha-Beta algorithm, or enter NIL if no leaves were pruned. Enter a comma separated list of labels (A to D), or enter NIL. NO SPACES, TABS, DOTS, BRACKETS OR EXTRANEOUS CHARACTERS. Answer format: W,X,Y,Z Answers Case Sensitive : No
