Hi,
I am a new user for soplex4.0.0 and GMP. I was trying to solve an LP file (see google drive https://drive.google.com/open?id=10GjuxsKvz6gcIQ61HXNyfBFVmEDviHCY ) with coefficients up to 15 significant digits by using the code below:
/tools/build/bin/soplex -s0 -g5 -f1e-10 -o1e-10 -x -q -c --readmode=1 --solvemode=2 --int:checkmode=2 --real:fpfeastol=1e-3 --real:fpopttol=1e-3 test > test.lp.out
Currently this code takes more than 2hour and generate a huge out file during the calculation. I attached an out file here as test.lp.out. Could you help me to see where is the problem and what should I do to fast the progress but keep the precision higher than 10-11. Many thanks!
Best,
Feiran
