  • A model for optimal fleet composition of vessels for offshore wind farm maintenance 

    Gutierrez-Alcoba, Alejandro; Ortega, Gloria; Hendrix, Eligius M.T.; Halvorsen-Weare, Elin Espeland; Haugland, Dag (Elsevier, 2017)
    We present a discrete optimisation model that chooses an optimal fleet of vessels to support maintenance operations at Offshore Wind Farms (OFWs). The model is presented as a bi-level problem. On the first (tactical) level, ...

  • Parameterized complexity of the spanning tree congestion problem 

    Bodlaender, Hans L.; Fomin, Fedor; Golovach, Petr; Otachi, Yota; van Leeuwen, Erik Jan (Springer, 2012-09)
    We study the problem of determining the spanning tree congestion of a graph. We present some sharp contrasts in the parameterized complexity of this problem. First, we show that on apex-minor-free graphs, a general class ...

  • Community Detection on the GPU 

    Naim, Md.; Manne, Fredrik; Halappanavar, Mahantesh; Tumeo, Antonino (IEEE, 2017)
    We present and evaluate a new GPU algorithm based on the Louvain method for community detection. Our algorithm is the first for this problem that parallelizes the access to individual edges. In this way we can fine tune ...

  • A domain-specific dialect for financial-economic calculations using reactive programming 

    Marheim, Christian Lundekvam (The University of Bergen, 2017-08-19)
    This thesis investigates to what extent reactive programming is suited for the implementation of systems that support banks in providing financial-economic advice to their private customers. To this end, we built a small ...

  • Visual Analysis of Protein-Protein Interaction 

    Horne, Marius Tendeland (The University of Bergen, 2017-08-15)
    Over the last decade there has been a steady increase in the focus of research into Protein-Protein docking. The Docking software provides a plausible configuration to a Protein-Protein Interaction. The docking will also ...

  • Model Checking with the Sweep-Line Method 

    Lilleskare, Andreas (The University of Bergen, 2017-06-21)
    Explicit-state model checking is a formal software verification technique that differs from peer review and unit testing, in that model checking does an exhaustive state space search. With model checking one takes a system ...
