Just yesterday I received a report from Energy Research Institute
(Russian Academy of Sciences). They use Glpk to model and forecast
the development of electroenergetics in Russia and report that they
successfully solved several LP models with about 250,000 variables
and 100,000 constraints, and plan to use Glpk for larger LP models
with about 400,000 variables and 150,000 constraints. (They don't
use MathProg; all data are provided in MPS format.)
