    Hello,

    I'd like to turn presolve off in the interactive optimizer. Is it possible and if yes, what's the path to the option ?

    Thanks !

    Many CPLEX features are controlled by parameters, which you can specify in the Interactive Optimizer via the "set" command.  If you type "set" alone, you will see a menu of choices, some of which then lead you to further sub-menus.  In the case of your particular question, this approach will lead you to
      set preprocessing presolve no
    which turns off all the preprocessing on your model.  I encourage you to explore the other parameter choices found within the "set" command, and of course the documentation provided along with the product contains a complete listing in the Parameters Reference Manual.
