7 Aug 2007 ================================ 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 Linux-PC (3.2 GHz P4, 4 GB RDRAM, Linux-2.6).
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-1.4.0 https://projects.coin-or.org/Clp LPABO-6.0 http://www.orlab.org/software/lpabo/ (not accessible anymore) LPAKO-7.0 http://www.orlab.org/software/lpako/ (not accessible anymore) QSOPT-1.0 http://www.isye.gatech.edu/~wcook/qsopt/ SOPLEX-1.3.0 http://soplex.zib.de/ GLPK-4.20 http://www.gnu.org/software/glpk/

see also the LIPSOL results on http://plato.asu.edu/ftp/lpcom.txt LIPSOL-0.60 http://www.caam.rice.edu/~zhang/lipsol/

Times are user times in secs including input. "$" without crossover.
