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.

It is a standard exercise in dynamic programming to devise a polynomial time algorithm that constructs the optimal bitonic tour. [1] [2] Although the usual method for solving it in this way takes time , a faster algorithm with time is known. [3]

It consists of two paths, the upper and lower (imaging a line connecting the starting and end points), such that each point is visited by at least one of the paths. We describe a dynamic programming algorithm which uses partially constructed bitonic tours.
