Each of the following shows the sequence of directions and steps employed by an improving search that began at y102 = 12, 0, 52. Compute the sequence of points visited by the search.

(a) y112 = 13, -1, 02, l1 = 2, y122 =

1 -1, 2, 12, l2 = 5, y132 = 10, 6, 02, l3 = 12

(b) y112 = 11, 3, -22, l1 = 2, y122 =

11, 0, 22, l2 = 12

, y132 = 14, 3, 22, l3 = 12
