In this paper the authors report on numerical experiments with dynamic programming algorithms designed for solving problems with nonseparable objective functions of the C-programming type. The experiments were conducted with the view to evaluate the efficiency of C-programming’s exclusionary rules when they are incorporated in the conventional parametric Lagrangian search method. Two classical nonseparable problems are considered: (1) the variance minimization problem and (2) the nonlinear fractional knapsack problem. The results indicate that the incorporation of C-programming’s exclusionary rules in the Lagrangian procedure significantly improves the efficiency of the line search procedure.
