Consider the following MCTS tree with S1, S2, S3 are nodes such that Q(S2,a1) = 15 and Q(S3, a2) = 5. Let n(S2,a1) = 1 and n(S3,a2) = 3. Let value of S1= 20 and total visit to S1 becomes equal to n(S1) = 4. We follow Upper Confidence Tree (UCT) approach and set c =v2, and use log to the base 2 for calculations below. Answer the following questions - S1 Val = 20 n(S1) = 4 a 1 a2 S2 Val = 15 n(S2) = 1 S3 Val = 5 n(S3) = 3 What is the UCT value of node S2 in the above graph? Round off the value to the nearest integer. Your
