Here is a zip file with the 800 customer instances.
The instance names in blue are hyperlinks to files with corresponding detailed solutions. They have all been checked by our solution checker. Note that many best known solutions do not have a reference to a peer reviewed publication. For these, important details on the solution algorithm, the computing time, and the experimental platform are probably not available. Further, there is no guarantee that the solutions have been produced without using external information, such as detailed solutions published earlier. We may later introduce two categories: 'properly published' and 'freestyle', the latter with no restrictions.
NB! The R_1_8_1 entry has been changed to an inferior value. The previous entry was based on a report without a detailed solution. Later, it appeared that the solution is infeasible, see reference NBD.
The updated entry is based on a detailed solution that has been checked by our solution checker.
