I was using the Cplex optimization studio 12.4 till now when i upgrade to 12.6. But i am facing a problem. In my model at some point I have to relax all integer variables. It works fine with the 12.4 and i checked it when i export the model in .lp file. But in the 12.6, with the same function "convertAllIntVars()" i still have the binary variables present in the .lp file. Can u explain me why. Thanks

Hi,

you will see that

RS01566Using convertAllIntVars on a submodel that contains only binary variables might not give a continuous model.

is fixed with the fix pack
