Here you find instance definitions and the best known upper and lower bounds (to our knowledge) for the 23 instances of the mggdb (ß=0.25) benchmark derived from the CARP by Bosco et al. [BLMV]. The values for the upper and lower bounds reported in the table only include traversal costs, i.e. service costs are omitted.
Instance definitions (text)
The mggdb_0.25 instance definitions can be found, as a zip-file here.
