WebThe 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] Although the usual method for solving it in this way takes time , a faster algorithm with time is known.
