Upcoming Webinar: Non-Convex Quadratic Optimization

January 14th - January 15th, 2020

Please join us for our upcoming webinar

One major new feature in Gurobi 9.0 is a new bilinear solver, which allows users to solve problems with non-convex quadratic objectives and constraints (i.e., QPs, QCPs, MIQPs, and MIQCPs). Many non-linear optimization solvers search for locally optimal solutions to these problems. In contrast, Gurobi can now solve these problems to global optimality. Non-convex quadratic optimization problems arise in various industrial applications. In particular, non-convex quadratic constraints are vital to solve classical pooling and blending problems.

In this webinar session, we will:

  • Introduce MIQCPs and mixed-integer bilinear programming
  • Discuss algorithmic ideas for handling bilinear constraints
  • Show a live demo of how Gurobi 9.0 supports bilinear constraints by building and solving a small instance of the pooling problem

This webinar will be presented by:

Dr. Tobias Achterberg, Director of Development at Gurobi Optimization. Dr. Achterberg studied mathematics and computer science at the Technical University of Berlin and the Zuse Institute Berlin. He finished his PhD in mathematics under supervision of Prof. Martin Grötschel in 2007. Dr. Achterberg is the author of SCIP, currently the best academic MIP solver. In addition to numerous publications in scientific journals, he has also received several awards for his dissertation and for SCIP, such as the Beale-Orchard-Hays Prize. From 2006, Dr. Achterberg worked for ILOG / IBM as developer of CPLEX in versions 11 to 12.6. Since 2014, he has been involved as a Senior Developer in the development of the Gurobi Optimizer.

Dr. Eli Towle has a PhD in Industrial and Systems Engineering from the University of Wisconsin – Madison. His research focused on stochastic network interdiction problems with applications to nuclear weapons smuggling. He also explored theory for improving relaxations for a broad class of nonconvex optimization problems.
