Embedding large-scale graph and text-based
datasets with LLMs 2025
with Annika Buchholz, Imene Khebouri, Thorsten Koch, Ida Litzel and Thi Huong Vu
Publication, Zuse Institute Berlin, Graph Theory
We propose an embedding method for large scale graph- and text-based data and implement it on the Web of Science dataset, containing 56 million scientific publications, revealing a self-structured landscape of texts.

Developing heuristic solution techniques for large-scale unit commitment models 2025
with Nils-Christian Kempke, Bassel Katamish, Charlie Vanaret, Shima Sasanpour, Jan-Patrick Clarner, Thorsten Koch
Publication, Zuse Institute Berlin, Integer Programming
Shifting towards renewable energy sources and reducing carbon emissions necessitate sophisticated energy system planning, optimization, and extension. This article considers a set of large-scale decarbonization-focused unit commitment models with expansion decisions and investigates a series of heuristics as a standalone solution method.

Solving the n-Queens Problem in Higher Dimension 2024
Publication, Zuse Institute Berlin, Integer Programming, Graph Theory, Chess
We present an integer programming formulation of the n-queens problem in higher dimensions and several strengthenings through additional valid inequalities. Compared to recent benchmarks, we achieve a speedup in computational time between 15-70x over all instances of the integer programs.

The n-Queens Problem in Higher Dimensions
2023
Thesis, Integer Programming, Graph Theory, Chess, Technical University Berlin
How many mutually non-attacking queens can be placed on a d-dimensional chessboard of size n?
A comprehensive overview on theoretical results, bounds, solution methods and the interconnectivity of the problem within topics of discrete optimization and combinatorics.

Dissonance Within 2023

Show, Cultural History and Theory
Participatory exhibition at Zwitschermaschine Berlin.
Dall-ix 2023
with Erik Anton Reinhardt
Game, Cultural History and Theory
Historically, intelligence is perceived as human through play. Recently, responses that are not verifiable have led to the perception of intelligence increasingly shifting towards plausibility instead.
We demonstrate that cultural affirmation is desired, or even necessary, for human plausibility and, thus, the perception of intelligence.

Computing bounds for ranks and qualification of the DPC
2023
Blog, Integer Programming, DotA, Zuse Institute Berlin
The Elimination Problem in sports asks whether a team can still achieve a particular result given the current standings of the league and its structure.
In DotA, the major goal of many teams during a season is to qualify for The International (TI), as its prize money and prestige are unmatched. This motivates the question to find individual provable bounds for qualification to TI — in other words: How many points does a certain team need to be qualified for TI at a given point in time?
More stitches, less riches
2023
Software, University of the Arts Berlin
In More stitches, less riches the dolphin fresco of the Minoan palace of Knossos continuously extends, applying outpainting methods. Viewers may engage in the process of restoration, decay and distortion. The work connects the exploitative management of the archaeological site to the question, whether a similar distorting effect on the cultural cycle is emergent through generative models.
Politics of Seating 2023
in collaboration with the design project Hybrid Occasions at UdK Fashion
Show, University of the Arts Berlin, Integer Programming
Stage design and seating for runway shows inevitably impose what Kondo calls the politics of seating. Desirable seats are allocated with consideration, the importance becomes a signifier of status.
The question arises if stage and space can be imagined in ways that level and amplify the experience for the audience overall, eroding the spatial hierarchies.

Knight’s Yarn
2022
with Lilith Hoffmann
Blog, Chess
The knight tour on an infinite chess board is a sequence of knight moves during which the knight may only visit each square once. Each subsequent move is determined by choosing the next square closest to the origin.
We compute the sequence of moves for a knight on an infinite three-dimensional chessboard, asking whether the knight also gets trapped, and if so, when?
