Sep 29, 2008 · Find the length of the optimal complete (closed) bitonic tour. This is done by choosing the shortest tour from the set of all possible complete tours. A possible closed tour is composed of a partial tour with rightmost point R as one of its endpoints plus the final return segment from R to the other endpoint of the tour.

Shortest bitonic tour. Ask Question Asked 3 years, 11 months ago. Active 3 years, 11 months ago. Viewed 329 times 2 \$\begingroup\$ This a solution to the shortest bitonic tour using dynamic programming. Bitonic tour starts at the leftmost point then goes strictly rightward to the rightmost point and finally strictly leftward to the starting point.

Hence, the tour cannot be bitonic. Observation 1 implies that edge (p n−1,p n) is present in any bitonic tour that visits all points. Hence, to find a shortest such tour, it suffices to concentrate on minimizing the length of the bitonic path from p n−1 to p n that is obtained by removing edge (p n−1,p n) from the tour.

In an optimal bitonic tour, one of the points adjacent to pn must be pn−1, so b[n,n] = b[n − 1,n] + pn−1pn. To reconstruct the points on the shortest bitonic tour, we define r[i,j] to be the index of the immediate predecessor of pj on the shortest bitonic path Pij. Because the immediate predecessor of p2

(In this case, shortest.) The essential property of a bitonic tour is that a vertical line in the coordinate system crosses a side of the closed polygon at most twice. So, what is a bitonic tour of exactly two points? Clearly, any two points form a (degenerate) bitonic tour. Three points have two bitonic tours ("clockwise" and "counterclockwise").

tention to bitonic tours, that is, tours that start at the leftmost point, go strictly rightward to the rightmost point, and then go strictly leftward back to the starting point. Figure 15.11(b) shows the shortest bitonic tour of the same 7 points. In this case, a polynomial-time algorithm is possible.

We obtain two main results. First, for the case where the points have distinct integer x-coordinates, we prove that a shortest bitonic tour (which can be computed in O(nlog2n) time using an existing algorithm) is guaranteed to be a shortest tour overall when δ≤22–√, a bound which is best possible.

Figure 15.9(b) shows the shortest bitonic tour of the same 7 points. In this case, a polynomial-time algorithm is possible. Describe an O(n 2)-time algorithm for determining an optimal bitonic tour. You may assume that no two points have the same x-coordinate. (Hint: Scan left to right, maintaining optimal possibilities for the two parts of the ...
