Abstract
It is proved that an optimal {e, 1}n solution to a “e-perturbed” discrete minimum weight problem with constraints on compliance, von Mises stresses and strain energy densities, is optimal, after rounding to {0, 1}n, to the corresponding “unperturbed” discrete problem, provided that the constraints in the perturbed problem are carefully defined and e > 0 is sufficiently small.
