Hopefully, by now you'll be intrigued, and a bit more inclined to think that (or even exact solutions) for all these problems can be foundīy formulating them in a sum of squares optimization framework. Or, more generally, problems that deal with basic semialgebraic sets (setsĭefined by polynomial equalities and inequalities).Īlthough most of these problems are NP-hard, it turns out that useful bounds.Distinguishing separable from entangled states in quantum systems.Finding Lyapunov or Bendixson-Dulac functions for nonlinear dynamical.Mixed continuous-discrete optimization.Constrained or unconstrained optimization of polynomial functions.While this looks quite nice, perhaps you are actually interested in more The objective function is linear and the set of feasible u_i is convex. This is a convex optimization problem, since
Here, the A_ij(x) are multivariate polynomials, and the decision variables What is a "sum of squares optimization program"? WhyĪ sum of squares (SOS) program, in the simplest case, has the form: All these are well-known semidefinite programming solvers, with SOSTOOLS handling internallyĪll the necessary reformulations and data conversion. The SOS programs can be solved using SeDuMi, SDPT3, CSDP, SDPNAL, SDPNAL+, CDCS, SDPA and MOSEK. Simple, flexible, and intuitive high-level notation. SOSTOOLS canīe used to specify and solve sum of squares polynomial problems using a very
