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

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").

The results show that the approximate algorithm implemented provides very high quality tours in comparison with the Bitonic tours for the weight files which satisfy the weight condition. In the case of the weights being Euclidean distances in the unit square, the approximate algorithm provides a higher quality tour than the bitonic algorithm.

This is my implementation of Bitonic Tour (simplification of the Traveling Salesman Problem). Tests are not done very well, but it is not the point. I would be particularly interested in the comments on architecture and performance.

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.

Bitonic Sort - GeeksforGeeks

https://www.geeksforgeeks.org/bitonic-sort/

Background . Bitonic Sort is a classic parallel algorithm for sorting. Bitonic sort does O(n Log 2 n) comparisons.; The number of comparisons done by Bitonic sort are more than popular sorting algorithms like Merge Sort [ does O(nLogn) comparisons], but Bitonice sort is better for parallel implementation because we always compare elements in predefined sequence and the sequence of comparison ...

A solution to Bitonic euclidean traveling-salesman problem

https://www.cs.helsinki.fi/webfm_send/1452

A solution to Bitonic euclidean traveling-salesman problem We are given an array of n points p1, …, pn. We can assume that this array is sorted by the x-coordinate in increasing order, otherwise we could just sort it O(n*log(n)) time and the time complexity of this algorithm wouldn't change. For each index i=1..n-1 we will calculate what is the
