Oct 03, 2015 · Bitonic tour. Oct 3, 2015. In computational geometry the bitonic tour of a set of points is a closed polygonal chain formed by all the vertices in the set and that has the property of intersecting at most twice with any vertical line.. An example trace. As an example the following is not a bitonic tour while the following is

Yes, definitely a problem I was studying at school. We are studying bitonic tours for the traveling salesman problem. Anyway, say I have 5 vertices {0,1,2,3,4}. I know my first step is to sort these in order of increasing x-coordinates. From there, I am a bit confused on how this would be done with dynamic programming.

The TSP is NP-complete in the general case is NP-hard even in the Euclidean case and its solution is believed to require more than polynomial time. A dynamic programming algorithm has been designed for a special case of the TSP, the Bitonic TSP. A bottom-up approach has been used to implement the recursive algorithm.

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.

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.

Given a traveling salesman problem (TSP) tour H in graph G, a k-move is an operation that removes k edges from H and adds k edges of G so that a new tour H′ is formed.
