The paper represents a continuation of the work the author previously published in this journal for unconstrained problems. An interval (box) valued function, the so-called zone function, is introduced in the first section. The next section uses the new notion for finding global minima of continuous multivariate real functions over a set given by nonlinear inequality constraints. Two numerical examples are presented in the third section. The second numerical example gives a better approximation to a welded tubular structure problem than one that has appeared in the literature.
