Polynomial Optimization
07-28, 11:00–11:30 (US/Eastern), 32-155

Polynomial Optimization can be solved in a variety of ways. JuMP provides an unified interface for modelling these problems. In this talk, we show how to interface each type of polynomial optimization solver to this model and how they compare on a variety of benchmark problems.


Polynomial Optimization can be solved in a variety of ways. Black-box solvers using first and second-order derivative callbacks can be used but these only find a local extremum and cannot guarantee its global optimality. Several approaches exist to find the global optimum. These include Sum-of-Squares, Sums of AM/GM Exponential, multivariate partitioning algorithm and Algebraic System solving of the KKT conditions. In this talk, we detail the work of bringing all these possible solving strategies to the common JuMP nonlinear interface. We then compare the efficiency of these approaches both in theory and in practice on a variety of benchmark problems.
