This website serves as a repository for all of the asymmetric traveling salesman problems used as part of my doctoral research. The website is organized around the four main sources for these instances -- the TSPLIB, Cirasella, et al (2001), a real-world drayage problem from the Port of Rotterdam (PK Instances), and a drayage problem instance generator (crane2 instances). There is also a page containing the optimal values (when known) for these instances. Finally, there is a page with the source code and relevant files for converting (via a 2-node transformation) an ATSP into an STSP.
My use of these instances is documented in:
