Abstract
We investigate constrained supinf problems for functions of two variables. Conditions are given which assure that the objective function can be perturbed by continuous functions with arbitrary small norms in such a way that the supinf problem for the perturbed function has a solution. We also give a characterization of the notion of well-posedness for such problems.
