ILOG CPLEX 11.0 User's Manual > Programming Considerations > Developing CPLEX Applications > Eliminating Common Programming Errors > Solve the Problem You Intended

Your application may inadvertently alter the problem and thus produce unexpected results. To check whether your application is solving the problem you intended, use the Interactive Optimizer, as in Using the Interactive Optimizer for Debugging, and the diagnostic routines, as in Using Diagnostic Routines for Debugging.

You should not ignore any ILOG CPLEX warning message in this situation either, so read your messages, as in Read Your Messages.

If you are working in the Interactive Optimizer, you can use the command display problem stats to check the problem dimensions.
