Hi,

I have two IP models that should have the same optimal objective value judging from the way they are created, and in fact another MILP solver gives me an objective of -176.0 for both. Cbc (used through NEOS and also through google's or-tools' JAVA interface) gives me -175.0 and -176.0 respectively.

Is there any suggestion on what I am missing here? I attach mps and lp files for both models.

Thanks, Sven
