Assignment 2 Q5 Alpha-Beta Pruning

Hi there. Some input will be great here.

For question 5, here are the steps that I have followed but I am not convinced that it is correct.

1. From the bottom "Leave" nodes I choose the minimum values and prune the secondary nodes if the first node of that branch is already smaller than the first smallest node from the left.

2. These minimums from step 1 I now promote to the second level from the bottom . I.E. "H,I,J,K,L,M,N"

3. On this "H,I,J,K,L,M,N" level I now choose the max values and promote those to the next level "D,E,F,G" pruning as I go along.

4. On the "D,E,F,G" level I now chose the Minimums again and promote them to "B,C"

5. Finaly from the "B,C" level I choose the Maxim again and promote to "A"

Was this approach correct?
