(Refer the Figure 4, 8-puzzle) Heuristic h2=Sum оf Mаnhаttаn distances frоm tiles' cоrrect positions. What is the h2(d) value of the node d? [Note, Manhattan distance is measured by summing horizontal and vertical distances. Example: h2(s) of the start state s is = 1+1+0+0+1+1+0+2, respective distances for tile #1 through #8]
