  • Cheng, Eddie; Li, Li; Liptak, Laszlo; Shim, Sang Ho; Steffy, Daniel E. (Graphs and Combinatorics, 2017)
    In this paper we work to classify which of the (n, k)-star graphs, denoted by Sn,k , are Cayley graphs. Although the complete classification is left open, we derive infinite and non-trivial classes of both Cayley and ...
  • Shim, Sang Ho; Chopra, Sunil; Cao, Wenwei (Mathematical Programming, 2017)
    In this paper we identify strong facet defining inequalities for the master knapsack polytope. Our computational experiments for small master knapsack problems show that 1 / k-facets for small values of k ( k≤4 ) are ...
  • Chopra, Sunil; Filipecki, Bartosz; Lee, Kangbok; Ryu, Minseok; Shim, Sang Ho; Vyve, Mathieu Van (Mathematical Programming, 2017)
    We introduce a strong extended formulation of the convex recoloring problem on a tree, which has an application in analyzing phylogenetic trees. The extended formulation has only a polynomial number of constraints, but ...
  • Mohamed, Nader; Al-Jaroodi, Jameela; Jawhar, Imad; Idries, Ahmed; Mohammed, Farhan (Technological Forecasting & Social Change, Elsevier., 2018)
    Foreseeing changes in how smart cities manage their resources and provide services to the residents; research, development and production in various relevant technology fields is accelerating. Taking advantage of recent ...
  • Mohamed, Nader; Al-Jarood, Jameela; Lazarova-Molnar, Sanja (IEEE Access, 2019)
    Factories use many manufacturing processes that consume a lot of energy and highly contribute to greenhouse gas emissions. The introduction of the concept of Industrial Internet in USA and Industry 4.0 in Europe offers ...
