Dr. Dominik Michael Krupke
PostDoc Researcher in the Algorithms Division (IBR) at University of Technology in Braunschweig, Germany. I am interested in most aspects of algorithms and data structures, but my expertise lies in optimizing difficult, i.e., NP-hard, combinatorial problems with various techniques. My dissertation showcases large parts of my toolkit, including Mixed Integer Programming (Gurobi and CPLEX), Constraint Programming (CP-SAT of Google’s ortools), SAT-solvers, Dynamic Programming, Graph Algorithms, Approximation Algorithms, Reinforcement Learning, Meta-Heuristics, etc. There is a large overlap with the fields of Operations Research and Mathematical Optimization, but I prefer the term Algorithm Engineering as I am really focused on the algorithms and have primarily been educated by theoretical computer scientists. Thus, I am not just interested in just applying and combining these tools but also to understand how and why they work so well (or don’t). Currently, I am especially fascinated by CP-SAT because it smartly combines a lot of techniques, some of which seem unwise on first sight but work surprisingly well.
My preferred programming languages are Python and C++ (if Python is too slow or if I want to play with low level stuff).
Outside the university, I like to test and expand my physical limits in weight lifting (currently at nearly 2.5x own body weight in DL) and Krav Maga. My preferred means of transport have two wheels (cyclocross bicycle and motorcycles).
Research Agenda
The following is a draft of my research agenda, which I am currently working on. If you have any feedback, please let me know: I am still a relatively young PostDoc, trying to become an independent researcher (aka professor).
Exploring and Improving Techniques to solve NP-hard Problems
Nearly a decade ago, I was introduced to a versatile tool - Mixed Integer Programming (MIP) - which I likened to a hammer. Many NP-hard problems resembled nails, requiring only a few hits from the right angle to solve them. Supported by approximation algorithms and meta-heuristics, I achieved optimal or near-optimal solutions for many problems. However, with further study, I recognized some limitations of MIP's Branch and Cut-algorithm for certain problems. This realization prompted me top explore alternatives like Constraint Programming (CP) and SAT-solvers, which proved fruitful where MIP faltered. Since then, I've been driven by curiosity to experiment with new techniques, comprehend their inner workings, acknowledge their limitations, and combine them into more powerful tools.
A highly effective framework I've employed in the recent years involves a specialized variant of Large Neighborhood Search (LNS). This technique entails iteratively deconstructing small portions of a solution, leveraging tools like MIP or CP for repair. The key lies in an intricate understanding of the problem's nuances to identify precise segments for deconstruction and establish effective repair strategies. This can necessitate the integration of multiple orthogonal strategies, enabling the seamless fusion of diverse techniques to tackle a problem. A notable, recent accomplishment in this framework is SampLNS (WIP), which uses a CP-SAT-based LNS for optimization, supported by an MIP-based LNS on an auxiliary problem for computing lower bounds and breaking symmetries, with dynamic parameter adaptation after each iteration. We can also use techniques like MIP to easily improve the performance of meta-heuristics, such as computing optimal cross-overs in population-based approaches.
Central to my research agenda is to further explore the possibilities of combining diverse techniques, especially within the (A)LNS framework. I believe that there are further problems that so far only allowed heuristic solutions, but can be solved to near-optimality with the right and adaptive combination of techniques. Additionally, there are only few researchers with a broad expertise in different techniques, which is necessary to identify the right combination of techniques. Note that there is a clear distinction to already well-established portfolio-solvers, such as CP-SAT, as the adaptive fusion happens deeper in the approach.

Coverage Path Planning
A problem class I have been intensively working on for a long time and from different angles is coverage path planning. In coverage path planning, an efficient trajectory has to be found that covers a given area. This problem is relevant in many applications, e.g., lawn mowing, cleaning, painting, or surveillance, but also notoriously difficult. I have been looking at the theoretical complexity of problem variants, devised approximation algorithms, engineered those, implemented MIP-models, Large Neighborhood Search (LNS) heuristics, and how to deal with polygonal instead of grid environments. One of the latest results uses Close-Enough TSP as a subroutine to compute near-optimal tours and lower bounds for covering a polygon with a circular tool, without the restriction to a grid environment. We are currently working on an improved Close-Enough TSP-solver based on a custom Branch and Bound algorithm, to expand the applicability of the approach to larger instances. Extensions to TSP with Neighborhoods and routing around obstacles are also planned and partially already under development. Additionally, I am planning to develop an exact Close-Enough TSP with Turn Costs-solver, and use it to also compute bounds for the problem of covering a polygon with a circular tool with turn costs.

Optimizing Problems with Turn Costs
Above, I already mentioned my deep interest in computing coverage tours with turn costs, but I am also interested in turn costs in general. Many problem definitions ignore the dynamics and only consider distance costs. However, in many real-world applications, turn costs are also relevant. Unfortunately, they often significantly increase the complexity of the problem, but at the same time, they also make the problem more interesting and realistic. I intend to explore further problems with turn costs in the future, especially the above-mentioned Close-Enough TSP with Turn Costs.

Multi-Agent and Swarm Problems
Parallelization is not only useful in algorithms, but also in the real world. Systems with multiple agents can often solve problems faster and more efficiently than a single agent. However, this requires coordination between the agents, which is often difficult to achieve. I am planning to extend my work on coverage path planning to multi-agent systems and also to look into Multi-Agent Path Finding (MAPF) in general. The aspects of distributing the load and to coordinate the agents, i.e., preventing collisions, are interesting and challenging.

Other Geometric Optimization Problems
I have also been working on various other problems in computational geometry, such as computing minimal polygons with holes from a given set of points. Computing simple polygons would just be the euclidean Traveling Salesman Problem, but allowing holes can make some subtours legal. This requires specially created cuts that only disallow subtours that are not feasible holes, which of course can depend on the outer boundary. Assembly problems are also interesting and challenging, as the individual parts can have intricate dependencies. With being a co-organizer and technical lead of the CG:SHOP competitions, I am of course also in constant contact with various other problems in computational geometry, even if I am not actively working on them.
I am planning to go deeper into using SAT-solvers for assembly problems. There is already work in progress on k-Handed Assembly, and maximizing the constructable part in Tilt Assembly resp. minimizing the necessary auxiliary parts.

Methodology for Algorithm Engineering
Algorithm Engineering requires many skills on top of just algorithm design and writing efficient code. While there are cases in which it is sufficient to just do a quick implementation, run a benchmark, and print the results in a table, things quickly get more complicated to a level that can no longer be handled without a proper methodology.
First, the algorithm implementation and the evaluation framework needs to be reusable, so that it can be used by others, for verification but also to build upon it. As soon as the implementation has complex dependencies or is not trivial to use, it is not enough to just share the code, but it needs to be packaged and documented. There are modern tools to help with this, but they require some effort to learn and use. Too often, this leads to the situation that the code is not shared at all, or only in a way that is not usable by others. This is problematic as it limits the scalability of research, if everyone has to reinvent the wheel. We like to share our code as easy to use Python-packages, but as we often use C++ for performance-critical parts, we also have to deal with the problem of sharing C++-code and including complicated dependencies, such as CGAL. This requires a lot of work and understanding of the tools, and unfortunately, there is no textbook I know of that you could just press into the hands of a student to learn it.
Second, evaluations can quickly become very complex, and it is easy to make mistakes. The complexity of the evaluation explodes exponentially with the number of parameters you want to evaluate. It takes experience to design experiments that are not only correct but also efficient and comprehensible. You often need to split your evaluations into multiple parts, which requires a structured workflow and documentation to keep track of everything. Some experiments can take weeks to finish and create tens of gigabytes of data, which needs to be managed and analyzed. As you usually also iterate on your implementation, as you get new ideas or find bugs, you need to make sure that the data remains consistent and comparable, without having to rerun everything. This is a lot of work with many pitfalls, and it is often left to the junior researchers to figure out on their own. This is especially problematic for junior researcher that can not leverage the experience of a senior researcher (with fresh hands-on experience), as it is rarely described in papers.
Other disciplines, such as machine learning, bioinformatics, etc., struggle with similar problems, and I am planning to survey how they deal with it. Their communities are often much larger, and they have more resources to develop tools and methodologies, such as Scientific Python. I also already started to develop tools to help with it, such as slurminade, a decorator-based helper for distributing Python with Slurm, and AlgBench, a framework for managing and analyzing experiments. For helping building Python packages with C++-extensions, I am working on skbuild-conan, which is an extension of scikit-build that allows you to use conan to manage your C++ dependencies. Additionally, I have prepared examples and try to document my workflows of current and future projects, to help others to get started. However, this is a serious amount of work and requires a lot of experience, such that I am planning to reach out to other researchers to work on this together. I spent already a lot of time on this, but I believe it is worth it as it will help to scale research and improve its quality.

Teaching Algorithm Engineering
I served for multiple years as technical lead for the CG:SHOP challenges, which motivates the computational geometry community to tackle difficult optimization problems. Together with my colleague Phillip Keldenich, I developed a new course on Algorithm Engineering, teaching the methodology to solve NP-hard problems and to implement algorithms efficiently. To get students interested, I also offer a beginner-friendly algorithm lab that lets students use a few tools such as MIP-solvers, SAT-solvers, and CP-solvers as a black box to solve NP-hard problems. Originating from the algorithm engineering course, I started writing a (well-received) primer on Google's CP-SAT solver, which is a powerful new tool for solving NP-hard problems. I believe that one needs to understand the tools to use them effectively, and it does in my opinion not yet have the necessary educational material for beginners to understand it. My future roadmap involves creating a tutorial and simple framework for implementing efficient branch and bound algorithms. This will deepen insights into existing implementations and provide a cornerstone for non-classical implementations, not yet supported by existing frameworks (e.g., our work on CE-TSP).

Connecting with other Fields
Many researchers in other fields have to deal with complex optimization problems, but they often do not have the necessary expertise to solve them efficiently, nor do they know that there are significantly better options than some meta-heuristics. I like to connect to different fields and look for problems that can be solved with my expertise. Additionally, I am a curious person and like to learn about what other people a curious about. Examples of fields I have already had contact with:
- Bioinformatics: Disease Module Mining, consulted on some DNA-assesmbly problem
- Software Engineering: SampLNS (WIP)
- Assembly: As seen above.
- Robotics: As seen above.
- Satellites
- Automotive Industry (Projects under NDA)

Machine Learning in Algorithm Engineering
The raise of LLMs (Large Language Models) like GPT-3 open exciting new opportunities for algorithm engineering, which I am eager to explore. They do not only show potential in helping to write, document, and debug code but also in tuning code. Further, they may help in analyzing the data of experiments and in detecting anomalies and patterns. For example, you could let an LLM read all the logs of your experiments and return suspicious logs that could be an undetected bug and should be investigated. While you should not rely on an LLM for that and definitely need to implement safety-measures yourself, it could help you find anomalies earlier. I have also been surprised by tools like Copilot, being able to help with writing MIP-models (though, it is also dangerous due to the ability to do nearly correct suggestions, with difficult to spot errors).
Of course there are also the obvious applications of using Machine Learning in the optimization itself, e.g., as a cost-function in an A* search, or for the algorithm selection problem. We have successfully use Deep Reinforcement Learning for the Gathering problem, beating our classical algorithms that were complete overhelmed by the complexity of the problem. However, the success stories of Machine Learning in optimization are still rare, and I am not sure that this will change soon. The classical algorithms already kind of learn automatically (e.g., CDCL), without the need for neural networks. I am still open to explore possibilities, though I believe that they will rather in parameter tuning and algorithm selection, than in the optimization itself. We also successfully used techniques from machine learning to select a subset of diverse instance from a huge set for the CG:SHOP competitions, but these were rather simple techniques such as k-means clustering.

Teaching
Phillip Keldenich and I offer the new course algorithm engineering, which teaches you how to implement algorithms efficiently (lots of CPU and memory architecture) and to understand and use techniques for solving NP-hard optimization problems (MIP, CP, SAT, Heuristics). The course is aimed for master students and was first taught during summer term in 2022.
I assisted lectures in mathematical optimization, algorithm engineering, and approximation algorithms. Additionally, I supervised multiple software development labs, projects, and theses for students.
