TY - GEN A1 - Helmberg, Christoph A1 - Rendl, Franz A1 - Weismantel, Robert T1 - Quadratic Knapsack Relaxations Using Cutting Planes and Semidefinite Programming: extended abstract N2 - We investigate dominance relations between basic semidefinite relaxations and classes of cuts. We show that simple semidefinite relaxations are tighter than corresponding linear relaxations even in case of linear cost functions. Numerical results are presented illustrating the quality of these relaxations.
