Optimizing Car Resequencing on Mixed-Model Assembly Lines: Algorithm Development and Deployment
Andreas Karrenbauer, Bernd Kuhn, Kurt Mehlhorn +1
The mixed-model assembly line (MMAL) is a production system used in the automobile industry to manufacture different car models on the same conveyor, offering a high degree of prod…
Algorithm Engineering of SSSP With Negative Edge Weights
Alejandro Cassis, Andreas Karrenbauer, André Nusser +1
Computing shortest paths is one of the most fundamental algorithmic graph problems. It is known since decades that this problem can be solved in near-linear time if all weights are…
Engineering Insights into Biclique Partitions and Fractional Binary Ranks of Matrices
Angikar Ghosal, Andreas Karrenbauer
We investigate structural properties of the binary rank of Kronecker powers of binary matrices, equivalently, the biclique partition numbers of the corresponding bipartite graphs.…
A Survey of Approximability Results for Traveling Salesman Problems using the TSP-T3CO Definition Scheme
Sophia Saller, Jana Koehler, Andreas Karrenbauer
The traveling salesman (or salesperson) problem, short TSP, is a problem of strong interest to many researchers from mathematics, economics, and computer science. Manifold TSP vari…
Improving Order with Queues
Andreas Karrenbauer, Kurt Mehlhorn, Pranabendu Misra +4
Given a sequence of numbers and parallel First-in-First-Out (FIFO) queues, how close can one bring the sequence to sorted order? It is known that queues suffice to sort…
Physarum Inspired Dynamics to Solve Semi-Definite Programs
Yuan Gao, Hamidreza Kamkari, Andreas Karrenbauer +2
Physarum Polycephalum is a slime mold that can solve shortest path problems. A mathematical model based on Physarum's behavior, known as the Physarum Directed Dynamics, can solve p…
