    • Bounds on Linear PDEs via Semidefinite Optimization 

      Bertsimas, Dimitris J.; Caramanis, Constantine (2002-01)
      Using recent progress on moment problems, and their connections with semidefinite optimization, we present in this paper a new methodology based on semidefinite optimization, to obtain a hierarchy of upper and lower bounds ...

    • Applications of Semidefinite Optimization in Stochastic Project Scheduling 

      Bertsimas, Dimitris J.; Natarajan, Karthik; Teo, Chung Piaw (2002-01)
      We propose a new method, based on semidefinite optimization, to find tight upper bounds on the expected project completion time and expected project tardiness in a stochastic project scheduling environment, when only limited ...

    • Acceleration of Gas Bubble-Free Surface Interaction Computation Using Basis Preconditioners 

      Tan, Kiok Lim; Khoo, Boo Cheong; White, Jacob K. (2002-01)
      The computation of gas bubble-free surface interaction entails a time-stepping algorithm whereby a linear system is solved at each time-iteration. In our investigation, the linear systems are derived from a desingularized ...
