Abstract
This paper reports computational experience with the codesDecompsx andLift which are built on IBM's MPSX/370 LP software for large-scale structured programs.Decompsx is an implementation of the Dantzig-Wolfe decomposition algorithm for block-angular LP's.Lift is an implementation of a nested decomposition algorithm for staircase and block-triangular LP's. A diverse collection of test problems drawn from real applications is used to test these codes, including multinational energy models and global economic models.
