Sinopsis

Excerpt from Partitioning Algorithms for a Class of Knapsack Problems

In this paper algorithms are presented for evaluating the knapsack function for a class of two-dimensional knapsack problems such as arises, for example, in the solution of cutting stock problems in staged guillotine cutting operations. This class includes as a special case the classical one-dimensional knapsack problem. In each algorithm evaluation proceeds from the larger knapsack sizes to the smaller, exploiting for each size the optimality of all partitions or descendents of an optimal solution for a knapsack of that Size. All of the algorithms discussed are based on the methods of combinatorial programming and are reliable in the respect that if carried to completion they guarantee optimal evaluations for knapsacks.
