This paper identifies a Kuhn-Tucker point and demonstrates that for certain parameter values it is not optimal. A policy generation procedure is presented; the purpose is to prevent convergence of a primal algorithm to this inferior policy, which satisfies the Kuhn-Tucker optimality conditions.application/pdfenIn CopyrightTechnical reportCS75026-Rhttp://eprints.cs.vt.edu/archive/00000804/01/CS75026-R.pdf
