Hougardy, Stefan, 2024, "Hard to Solve Instances of the Euclidean Traveling Salesman Problem", https://doi.org/10.60507/FK2/ESZ1QZ, bonndata, V1
In our paper Hard to Solve Instances of the Euclidean Traveling Salesman Problem (Mathematical Programming Computation (2021) 13:51-74) we construct a family of Euclidean instances for the Traveling Salesman Problem for which the integrality ratio of the subtour LP converges to 4... |

Hougardy, Stefan, 2024, "Triangular Grid Instances for the Euclidean Steiner Tree Problem", https://doi.org/10.60507/FK2/XLGFI4, bonndata, V1
This data set contains triangular nxk arrays with 2<=n, k<=10 using the TSPLIB-format. The instances where generated as part of the master's thesis of Daphne Rohrssen written 2022 under the supervision of Stefan Hougardy at the University of Bonn. Some of these instances are very... |
