We ask that you post in English, to give maximum audience to your questions and to enable others to benefit from your replies. If asking for help, please also mention the version number of CPLEX that you are using, which modeling or programming interface (e.g. OPL, Concert, Callable Library), and the language (e.g. Java, C#, C++) you are using, unless the context is already clear from your question.

If your question pertains more to the aspects of using the OPL modeling language, than to the solution technologies in the CPLEX Optimizers, we mention that there is also a forum for OPL at
