Hi, Translated MPS (fixed and freemps) and CPLEX (LP) from MathProg Model have 0.000 Objective function whereas the MathProg has correct objective function ( 7.153413121e+07)
What causes these problems, not getting the right results? The logs of the 2 models (MathProg and translated fixed MPS) below. Thanks.
