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. [1] [2]The problem of constructing optimal bitonic tours is often credited to Jon L. Bentley, who published in 1990 an experimental comparison of many heuristics for the ...

15-3 Bitonic euclidean - CLRS Solutions

J. L. Bentley has suggested that we simplify the problem by restricting our attention 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 …

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.

J.L. Bentley 建议通过只考虑双调旅程(bitonic tour)来简化TSP问题。,这种旅程即为从最左点开始，严格地从左到右直至最右点，然后严格地从右到左直至出发点。 双线性DP。 将一个人从最左端走到最右端，然后从最右端走到最左端等价成两个人同时从最左端不重复的走过中间的点并且到最右端。
