Stability of the Solution of Definite Quadratic Programs,

Abstract

The paper studies how the solution of the problem of minimizing Q(x) = 1/2(x sup T)Kx - (k sup T)x subject to Gx < or = g and Dx = d behaves when K, k, G, g, D, and d are perturbed, say by terms of size epsilon, assuming that K is positive definite. It is shown that in general the solution moves by roughly epsilon if G, g, D, and d are not perturbed; when G, g D, and d are in fact perturbed, much stronger hypotheses allow one to show that the solution moves by roughly epsilon. Many of these results can be extended to more general, nonquadratic, functionals. (Author)
