NAME

soplex - solve linear programming problems

SYNOPSIS

soplex

[ options ] lpfile

OPTIONS

lpfile

linear program as .mps [ .gz ] or .lp [ .gz ] file.

General options

--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

Limits and tolerances

	-t s		set time limit to s seconds
	-i n		set iteration limit to n
	-f eps		set primal feasibility tolerance to eps
	-o eps		set dual feasibility (optimality) tolerance to eps
	-l eps		set validation tolerance to eps

Algorithmic settings

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)

-s value

choose simplifier/presolver (0 - off, 1* - internal)

-g value

choose scaling (0 - off, 1 - uni-equilibrium, 2* - bi-equilibrium, 3 - geometric, 4 - iterated geometrix, 5 - least squares, 6 - geometric-equilibrium)

-p value

choose pricing (0* - auto, 1 - dantzig, 2 - parmult, 3 - devex, 4 - quicksteep, 5 - steep)

-r value

choose ratio tester (0 - textbook, 1 - harris, 2 - fast, 3* - boundflipping)

Display options

-v level

set verbosity to level (0 - error, 3 - normal, 5 - high)

	-x		print primal solution
	-y		print dual multipliers
	-X		print primal solution in rational numbers
	-Y		print dual multipliers in rational numbers
	-q		display detailed statistics
	-c		perform final check of optimal solution in original problem
