This page lets you download the benchmarks
used during the evaluation. Further information on these benchmarks
will be available later.
Each benchmark named file has
been normalized and renamed to normalized-opb-file.

Benchmarks obtained on the web
The comments in the

from.

Benchmarks translated from MPS files gathered on the web
These benchmarks are a translation of linear programming problems
available on the web and expressed in MPS format. These benchmarks are
named normalized-opb-vX-YY-ZZ-file where X is the version of the translator,
YY is the maximum number of
bits used for the representation of the integer part of a variable, ZZ is the number of bits used for
the representation of the fractional part of a variable and file is the name of the initial MPS
file.
Note that the translation process hasn't been thoroughly tested.
Therefore, the semantics of these files might be different from the
initial MPS file. Furthermore, the limitation on the number of
bits used to represent a real variable imposes constraints which
are not initially expressed in the MPS file. Therefore, the set of
solution is likely to be different. At last, the translation process
tends to generate huge coefficients that can exceed the limits of a 32
bits integer.
