Abstract:

The paper shows that the LP relaxation of the cutting-stock problem can be solved efficiently by the recently proposed inexact bundle method. This method saves work by allowing inaccurate solutions to knapsack subproblems. With suitable rounding heuristics, the proposed method solves almost all the cutting-stock instances from the literature.
