Abstract:

We consider the semi‐infinite optimization problem: f * min x X { f ( x ) : g ( x , y ) 0 , y Y x } equ1 via a (by now standard) hierarchy of semidefinite relaxations, and for increasing values of d. In practice d is fixed, small, and one relaxes the constraint θ d ≤0 to θ d (x)≤ϵ with ϵ>0, allowing us to change ϵ dynamically. As d increases, the limit of the optimal value f d ϵ equ2 is bounded above by f *+ϵ.
