Is Thinner Better? -- Cascade Knapsack Problems

Paper: Thinner is not Better (under preparation)

Given below are the CPLEX .lp files and AMPL .dat files for n=20 and 30 instances.
There are 10 instances given for each n. For each instance, the lp-files of the cascade
knapsack problem (4-CKP), the corresponding 2-level decomposable knapsack problem
(DKP), the CBR-reformulation problem of CKP, and the AMPL data files are given.

n = 20
n = 30

This AMPL model file can be used for all the relevant calculations.
The data file for the n=9 example in the paper (Example 1) is here.

AMPL model file for branching on CBR hyperplanes for marketshare problems.
Here are the corresponding data files for marketshare1 and marketshare2.

Options file for settings in AMPL.

You can also download ALL the files listed here as a single tar-bzip2-ed file here.
