Details of Computational Tests
Given below are the CPLEX .lp files and AMPL .dat files for the 10 instances with n=50. For each instance, the lp-files of the cascade knapsack problem (CKP), the CBR-reformulation problem of CKP, and the AMPL data files are given.
For examples 1-3 in the manuscript, this
alternative AMPL model
file can be used. Here are the AMPL data files for the
examples in the manuscript.
You can also download all the problem files listed above as a single tar-bzip2-ed file here.
