    Hello all,

    My model in C++/CPLEX is giving me the following error -

    Error : Using empty IloNumVar handle.

    All the declared variables are being used in the model constraints, so I assume they are all extracted. I am not able to figure out the source for this error. Any leads would be appreciated. Thanks!

    The exception IloEmptyHandleException is thrown if an empty handle is passed as an argument to a method, function, or class constructor.

    So please check your passed argument

    And how about paste your part code here?

    Thanks for your reply. I figured out the source of my problem last night. I was using cplex.getValue() to output the values of a set of 3-D variables, including variables whose indices were beyond the allowed bound. So getValue() was asked to provide values to variables which were never declared!!!

    Thank you again for your input!
