       -in    set iteration limit to n

       -feps  set primal feasibility tolerance to eps

       -oeps  set dual feasibility (optimality) tolerance to eps

       -leps  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)

       -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)

   Display options
       -vlevel
              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
