  1. 1. Applying quantum approximate optimization to the heterogeneous vehicle routing problem

    Författare :David Fitzek; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; variational quantum algorithm; Quantum computing; quantum approximate optimization algorithm; vehicle routing;

    Sammanfattning : Quantum computing offers new heuristics for combinatorial problems. With small- and intermediate-scale quantum devices becoming available, it is possible to implement and test these heuristics on small-size problems. LÄS MER

  3. 2. Accelerating column generation schemes : applications to routing problems

    Författare :Andreas Westerlund; Oli Madsen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Many integer optimization problems of great practical importance are today attacked with column generation. Merits of column generation is that it enables the use of compact and flexible formulations of many complex optimization problems, and that it often gives rise to good (strong) formulations. LÄS MER
