    On Computing a Buy/copy Policy Using the Pitt-Kraft Model
    Greenberg, Harvey J.; Kraft, Donald H. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1975)
    The Pitt-Kraft model of buying versus photocopying results in a small, but complex, nonlinear program. 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.
