# Optimal objective values for the Netlib LP models, one per line: name and value.
#
# Most come from the table in the Netlib README distributed with the models. That table omits
# the Kennington problems (CRE-*, KEN-*, PDS-*) and a few later additions, and gives STANDGUB
# as "(see NOTES)" rather than a number. Those nine were computed here instead, by solving with
# HiGHS and SCIP and requiring the two to agree to 1e-6 relative - marked (computed) below.
#
# The method checks out where both sources exist: STANDATA is 1.2576995000E+03 in the README and
# the solvers reproduce it exactly. STANDGUB is the same model with GUB markers, and the README
# notes say so - the computed value matches STANDATA, as it should.
# Three values here are not the ones in the README's main table:
#
# E226 the file carries an RHS entry of -7.113 on the objective row. By the MPS convention that is
# the negative of an objective constant, so the constant is +7.113. HiGHS, SCIP and ojAlgo all
# apply it and return -1.1638929066E+01. The README's -1.8751929066E+01 is the optimum without
# the constant - delete that RHS entry from the file and all three return exactly it. E226 is
# the only model in this set with a nonzero objective RHS entry.
#
# GREENBEA the main table says -7.2462405908E+07, but the README's own CPLEX/MINOS reference table says
# -7.2555248130E+07, and that is what HiGHS, SCIP and all four ojAlgo configurations return.
#
# PILOT the main table says -5.5740430007E+02, but the README's own CPLEX/MINOS reference table says
# -5.5748972928E+02 (CPLEX), and that is what HiGHS and ojAlgo return.
