    Hello All,

     

    I am trying to set the numerical emphasis precision parameter of an optimization program that calls CPLEX 12.9.0 in Java Eclipse by "cplex.setParam(IloCplex.Param.Emphasis.Numerical, 0);", but it has an error and wants me to change it to "cplex.tuneParam();". I appreciate any suggestions and help to resolve this issue. Does "cplex.tuneParam()" do the same thing as "cplex.setParam(IloCplex.Param.Emphasis.Numerical, 0)"?

     

    Thanks,

    The numerical emphasis parameter is a BooleanParam in the Java API, so you must set it to either true or false.

    Replace: 

    cplex.setParam(IloCplex.Param.Emphasis.Numerical, 0);

    With: 

    cplex.setParam(IloCplex.Param.Emphasis.Numerical, true);

    That should do the trick.
