Suppose you have performed a- pruning on a game tree with horizon h where you used a static evaluation function f(x) to estimate how good the positions at the horizon are. Now you realized that you made a mistake when computing f(x) and that a better heuristic is actually given by if f() 20 and How does this change in heuristic affect the previous pruning? Carefully justify your answer.
