It consists of two paths, the upper and lower (imaging a line connecting the starting and end points), such that each point is visited by at least one of the paths. We describe a dynamic programming algorithm which uses partially constructed bitonic tours. Web15.11(b) shows the shortest bitonic tour of the same 7 points. In this case, a polynomial-time algorithm is possible. Describe an O(n2)-time algorithm for determining an optimal bitonic tour. You may assume that no two points have the same x-coordinate and that all operations on real numbers take unit time. greeley vfw post 2121
