Dr. Tamás Terlaky's research interests include high-performance optimization methods, optimization models, algorithms and software, and solving optimization problems in engineering sciences. Specifically, he explores the following topics:

  • Interior Point Methods for linear and nonlinear optimization, Semidefinite Optimization, engineering applications;
  • Linear optimization, pivot methods, network flows, applications;
  • Sensitivity analysis, quadratic optimization, linear complementarity problems;
  • Nonlinear optimization, geometrical programming, lp programming, cutting plane and decomposition methods;
  • Applications of OR and optimization methods, especially in production, engineering, structural design, water management, optimizing nuclear reactors;
  • Integer and combinatorial optimization; and,
  • Oriented matroid programming.

Terlaky's HPC research includes imaging of cancerous tumors and how to radiate the tumor in the most effective way. Dr. Terlaky harnesses algorithms to optimize the core refueling process of nuclear reactors, the radiation effectiveness in cancer treatment, the maintenance scheduling of oil refineries, and more.

Dr. Terlaky is founding editor-in-chief of the journal, Optimization and Engineering and serving as associate editor of seven journals. He is a Fellow of the Fields Institute, Toronto, Canada, and received the MITACS Mentorship Award for his distinguished graduate student supervisory record.
