Re: [Help-glpk] Translated MPS (fixed and freemps) and CPLEX (LP) from MathProg Model have 0.000 Objective function whiel MathProg Model has correct one

Hi Andew,

Thanks Andrew.

Learn more tricks on dealing with mps and lp files now.

We have to put "--max"  or  probably "--min" as well in submitting /
passing these files in glpsol.

MPS and Cplex lp files work perfectly now.

Thanks.
