4) Minimax and Alpha-Beta Pruning [20 marks = 5+12+3] Max Min Max Min X 7 23 5 18 20 27 11 7 22 This is a minimax tree above, assume children are visited in left-to-right order. Show: i) What is the minimax value for the root? ii) Which of the leaf nodes will be pruned (using alpha-beta pruning)? Note: you should show some working (in simple text or with the tree in different stages) 1 ii) If the order of the 3 and 4th leaves (with values 6 and 19 respectively) were swapped, would it affect the number of leaf nodes that are pruned?
