  • Alfaki, Mohammed; Haugland, Dag (Chapter; Peer reviewed, Dagstuhl Publishing, 2011)
    The pooling problem is an important global optimization problem which is encountered in many industrial settings. It is traditionally modeled as a bilinear, nonconvex optimization problem, and solved by branch-and-bound ...
  • Alfaki, Mohammed (Master thesis, The University of Bergen, 2008)
    This thesis investigates three approaches to improve the performance of the Hamiltonian Monte Carlo algorithm. The first approach enhances the Hamiltonian Monte Carlo by suppressing random walk in the Gibbs sampling using ...
  • Alfaki, Mohammed (Doctoral thesis, The University of Bergen, 2012-06-18)
    Pipeline transportation of natural gas is largely affected by restrictions regarding gas quality imposed by the market and the actual quality of the gas produced at sources. From the sources, gas flow streams of unequal ...
  • Frimannslund, Lennart; El Ghami, Mohamed; Alfaki, Mohammed; Haugland, Dag (Peer reviewed; Chapter, The authors, 2012)
    We consider the standard pooling problem with a single quality parameter, which is a polynomial global optimization problem occurring among other places in the oil industry. In this paper, we show that if the feasible ...
