Transforming Constraint Programs to Input for Local Search
Jo Devriendt, Patrick De Causmaecker, Marc Denecker
Applying local search algorithms to combinatorial optimization problems is not an easy feat. Typically, human intervention is required to compile the constraints to input data for…
Solving systems of equations on antichains for the computation of the ninth Dedekind Number
Patrick De Causmaecker, Lennart Van Hirtum
We study systems of equations on antichains, together with a way to count the number of solutions. We start with a simple example, generalise and show more applications. One of the…
A computation of D(9) using FPGA Supercomputing
Lennart Van Hirtum, Patrick De Causmaecker, Jens Goemaere +4
This preprint makes the claim of having computed the Dedekind Number. This was done by building an efficient FPGA Accelerator for the core operation of the process, and pa…
Features for the 0-1 knapsack problem based on inclusionwise maximal solutions
Jorik Jooken, Pieter Leyman, Patrick De Causmaecker
Decades of research on the 0-1 knapsack problem led to very efficient algorithms that are able to quickly solve large problem instances to optimality. This prompted researchers to…
A prediction-based approach for online dynamic patient scheduling: a case study in radiotherapy treatment
Tu-San Pham, Antoine Legrain, Patrick De Causmaecker +1
Patient scheduling is a difficult task involving stochastic factors such as the unknown arrival times of patients. Similarly, the scheduling of radiotherapy for cancer treatments n…
Eigenspectra of solar active region long-period oscillations
G. Dumbadze, B. M. Shergelashvili, S. Poedts +3
We studied the low-frequency h (long-period h) oscillations of active regions (ARs). The investigation is based on an analysis of a time series…
