- Abstract summary: We propose and compare Constraint Programming (CP) and Quantum Annealing (QA) approaches for rolling stock assignment optimisation.
In the CP approach, we model the problem with an Alldifferent constraint, extensions of the Element constraint, and logical implications.
For the QA approach, we develop a quadratic unconstrained binary optimisation (QUBO) model.

- Abstract: We propose and compare Constraint Programming (CP) and Quantum Annealing (QA)
approaches for rolling stock assignment optimisation considering necessary
maintenance tasks. In the CP approach, we model the problem with an
Alldifferent constraint, extensions of the Element constraint, and logical
implications, among others. For the QA approach, we develop a quadratic
unconstrained binary optimisation (QUBO) model. For evaluation, we use data
sets based on real data from Deutsche Bahn and run the QA approach on real
quantum computers from D-Wave. Classical computers are used to evaluate the CP
approach as well as tabu search for the QUBO model. At the current development
stage of the physical quantum annealers, we find that both approaches tend to
produce comparable results.

The quantum approximate optimisation algorithm (QAOA) is at the core of many scenarios that aim to combine the power of quantum computers and classical high-performance computing appliances for optimisation.
We study factors that affect solution quality and temporal behaviour of four QAOA variants using comprehensive density-matrix-based simulations.
Our results, accompanied by a comprehensive reproduction package, show strong differences between QAOA variants that can be pinpointed to narrow and specific effects.

Multi-Object Tracking (MOT) is most often approached in the tracking-by-detection paradigm, where object detections are associated through time.
As these optimization problems are often NP-hard, they can only be solved exactly for small instances on current hardware.
We show that our approach is competitive compared with state-of-the-art optimization-based approaches, even when using of-the-shelf integer programming solvers.
