Dear all, I'm using Concert Technology

I defined many variables arrays in my code, for example  IloNumVarArray4 X(env,nC);

When I generate .lp file using cplex.exportModel("model.LP"); , names in this file don't match the actual names that I've used.  Such as "id1188 and id1189" instead of X's

My question is "Can I show the variables in .lp file with the same names?" such as X1121 or X[1][1][2][1]. I tried many commands such as " setNames" but they don't work

Thanks

What did the names look like you tried to set with setNames()? Characters like '[' or ']' are not allowed for names in LP files (see here), hence you will never be able to see names like X[1][1][2][1] in an LP file. Make sure that your names conform with the LP file format then setNames() should work fine.
