Abstract

Given a single feasible solution x_F and a single infeasible solution x_I of a mathematical program, weprovide an upper bound to the optimal dual value. We assume that x_Fsatisfies a weakened form of the Slatercondition. We apply the bound to convex programs and we discuss itsrelation to Hoffman-like bounds. As a special case, we recover a bounddue to Mangasarian [11] on the distance of a point to a convex setspecified by inequalities.
