报告内容简介:In this talk, we consider a bilevel polynomial optimization problem, where the constraint functions of both the upper-level and lower-level programs involve uncertain parameters. We employ the deterministic robust optimization approach to examine the bilevel polynomial optimization problem under data uncertainty by providing lower bound approximations and convergences of sum-of-squares relaxations for the robust bilevel polynomial optimization problem. More precisely, we show that the global optimal values of sum-of-squares relaxation problems are lower bounds of the global optimal value of the robust bilevel polynomial problem and they converge to this global optimal value when the degrees of sum-of-squares polynomials in the relaxation problems tend to infinity.
