 ====================================
 Benchmark of commercial 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!

B/D/P: barrier/dual/primal simplex

The following codes were tested:

 XP-B/D/P     http://www.dashoptimization.com/ (XPRESS-MP-15.20)
 CPLEX-B/D/P  http://www.cplex.com/ (ILOG-CPLEX-10.0)
 MOSEK-4.0.0.32 http://www.mosek.com (barrier)
 LOQO-6.06    http://www.princeton.edu/~rvdb/
 LIPSOL       linprog in Matlab 7.0

Times are user times in secs including input and crossover to a feasible basis
for all codes except LOQO and LIPSOL. "$" without crossover.
