5 Mar 2009 ================================ Benchmark of free LP solvers ================================ H. Mittelmann (mittelmann@asu.edu)

Logfiles of these runs at: http://plato.asu.edu/ftp/lp_logs/

This benchmark was run on a 2.667GHz Intel Core 2 processor under Linux.
The MPS-datafiles for all testcases are in one of (see column "s")
http://miplib.zib.de/ [1],
http://plato.asu.edu/ftp/lptestset/ [2]
http://www.sztaki.hu/~meszaros/public_ftp/lptestset/ (NETLIB[3], MISC[4], PROBLEMATIC[5], STOCHLP[6], KENNINGTON[7], INFEAS[8]) NOTE: files in [2-8] need to be expanded with emps in same directory!

The following codes were tested:
BPMPD-2.21 http://www-neos.mcs.anl.gov/neos/solvers/lp:bpmpd/MPS.html (run locally) CLP-1.10.0 https://projects.coin-or.org/Clp PCx-1.1 http://www-fp.mcs.anl.gov/OTC/Tools/PCx/ QSOPT-1.0 http://www.isye.gatech.edu/~wcook/qsopt/ SOPLEX-1.4.1 http://soplex.zib.de/ GLPK-4.36 http://www.gnu.org/software/glpk/
