NAME

soplex - solve linear programming problems

SYNOPSIS

soplex [options] lpfile

--readbas=basfile: read starting basis from file
--writebas=basfile: write terminal basis to file
--writefile=lpfile: write LP to file in LP or MPS format depending on extension
--writedual=lpfile: write the dual LP to a file in LP or MPS format depending on extension
--type:name=val: change parameter value using syntax of settings file entries
--loadset=setfile: load parameters from settings file (overrules by command line parameters)
--saveset=setfile: save parameters to settings file
--diffset=setfile: save modified parameters to settings file
--extsol=value: external solution for soplex to use for validation

Default settings are marked with *

--readmode=value: choose reading mode for lpfile (0* - floating point, 1 - rational)
--solvemode=value: choose solving mode (0 - floating-point solve, 1* - auto, 2 - force iterative refinement)
--arithmetic=value: choose base arithmetic type (0 - double, 1 - quadprecision, 2 - higher multiprecision)
--precision=value: choose precision for multiprecision solve (only active when arithmetic=2, possible values are 50, 100, and 200)
-svalue: choose simplifier/presolver (0 - off, 1* - internal)
-gvalue: choose scaling (0 - off, 1 - uni-equilibrium, 2* - bi-equilibrium, 3 - geometric, 4 - iterated geometrix, 5 - least squares, 6 - geometric-equilibrium)
-pvalue: choose pricing (0* - auto, 1 - dantzig, 2 - parmult, 3 - devex, 4 - quicksteep, 5 - steep)
-rvalue: choose ratio tester (0 - textbook, 1 - harris, 2 - fast, 3* - boundflipping)
