Abstract
In this paper, we study the train delivery problem which is a generalization of the bin packing problem, and is also equivalent to a one dimensional version of the vehicle routing problem with unsplittable demands. We give an APTAS for the general problem with time complexity \(O(n^{O(\epsilon^{-4})})\), which is better than the previous one \(O(n^{(\frac{1}{\epsilon})^{O(\frac{1}{\epsilon})}})\), where n is the number of input elements.
