WebAbstract. Fully polynomial approximation schemes for knapsack problems are presented. These algorithms are based on ideas of Ibarra and Kim, with modifications which yield better time and space bounds, and also tend to improve the practicality of the procedures. Among the principal improvements are the introduction of a more efficient method of ... Web1 jan. 1987 · The chapter provides an overview on the Lawler algorithm for the SPUG. The chaptre presents four integer programming formulations of the Steiner Problem in graphs, compares the linear relaxations of three of these formulations, and describes an application of Benders method to solve one of these formulations illustrated by an example.
