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... |

Heeren, Behrend; Sassen, Josua, 2023, "An Implementation of Nonlinear Discrete Shell Energies", https://doi.org/10.60507/FK2/YMRPMF, bonndata, V1
This C++ package provides a easy way to use nonlinear discrete shell deformation energies for triangle meshes described by Eigen matrices as used, for example, by libigl. Furthermore, it provides convenient interfaces for MATLAB (gptoolbox) and Python (libigl). |

Dual linear programming solutions and Python scripts that verify their feasibility. The dual linear programs for which feasible solutions are provided can be found in the provided README files. The linear programming solutions yield upper bounds on the approximability of the a pr... |
Hartwig, Florine; Sassen, Josua; Azencot, Omri; Rumpf, Martin; Ben Chen, Mirela, 2023, "Implementation of An Elastic Basis for Spectral Shape Correspondence", https://doi.org/10.60507/FK2/DXOEHJ, bonndata, V1
An implementation of a spectral non-isometric correspondence method that aligns extrinsic features using a functional map approach. To this end, we propose and use a novel crease-aware spectral basis derived from the Hessian of an elastic thin shell energy. |
Sassen, Josua; Hildebrandt, Klaus; Rumpf, Martin; Wirth, Benedikt, 2023, "The Freaky Torus", https://doi.org/10.60507/FK2/LORXU7, bonndata, V1
This dataset contains the Python code to compute samples on our shape space Freaky Torus of deformed tori, a synthetic shape space with factors S¹×S¹×T² The first factor, an S¹, controls the deformation of the latitudinal cross-section into a rotated ellipse. The next factor, ano... |

Nedelchev, Rostislav, 2023, "An Unsupervised Baseline For Dialogue Breakdown Detection Using Ouf-of-distribution Detection", https://doi.org/10.60507/FK2/MAVB6H, bonndata, V1
For the last several decades, a focus of artificial intelligence work has been computer-based systems for interacting with humans. Such a system must ensure smooth communication to provide thoughtful answers by interacting with the system. A major critical issue is they can creat... |

Nedelchev, Rostislav, 2023, "Evaluating Dialogue Systems via an Opinion", https://doi.org/10.60507/FK2/FX37GD, bonndata, V1
Dialogue systems are a significant field of research and development in artificial intelligence. Until today, the evaluation of such algorithms happens in one fundamental way. They solve "hypothetical problems," i.e., dialog systems are tested by being asked to respond in specifi... |
