This dataset contains the same instances as the previous releases, but also adds a number of restricted instances that are investigated in our paper "Optimization Approaches for the Traveling Salesman Problem with Drone". Furthermore, this version improves a small number of solutions to instances that were only very close to optimality in the 1.1 version of this dataset. The differences occured due to rounding issues in the IP-solver.
