We analyze the behavior of the feasible set in one class of semi-infinite optimization problems, inspired of an approximation of a given function, by means of functions belonging to a Haar space. We present a necessary and sufficient condition for the unicity of the approximation function from the Haar space. Continuity properties of the feasible set mapping have been investigated, as well.
