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

Bitonic tour - Wikipedia

Optimal bitonic tours. The optimal bitonic tour is a bitonic tour of minimum total length. It is a standard exercise in dynamic programming to devise a polynomial time algorithm that constructs the optimal bitonic tour. Although the usual method for solving it in this way takes time (), a faster algorithm with time (⁡) is known.. The problem of constructing optimal bitonic tours is often ...

Sep 29, 2008 · An open bitonic tour, optimal or not, has these properties: * it's bitonic (a vertical line crosses the tour at most twice) * it's open (it has endpoints), which we call "i" and "j" (i < j) * all points to the left of "j" are visited by the tour * points i and j are endpoints (connected to exactly one edge) * all other points in the tour are ...

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").

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.

Jul 01, 2019 · Write a function that takes an array as argument and returns the length of the longest bitonic subsequence. A sequence, sorted in increasing order is considered Bitonic with the decreasing part as empty. Similarly, decreasing order sequence is considered Bitonic with the increasing part as empty. Examples:

The bitonic tour, need to be a single line from the leftmost point to b. For example the solution of 0,4 looks like: There’s only one path satisfying the definition of a bitonic tour. That is the single line connecting all of the points that are smaller than or equals to b.
