Hello,

We have an application developed several years ago, this application generate a .mps file after that solve the model using Interactive Optimizer, write the solution .sol file and then that .sol file is readed by the application.

The problem is that we had an old version of CPLEX that write .sol file in a different format, now the CPLEX that we are using write the .sol in a XML format and the application can't read it. What option do we have in order to use the newest CPLEX version and to write the .sol in the old format?

Attached the the screenshot of the .sol 2 formats

Thank for your help

The code that writes out solution in this text format has been removed from the CPLEX code base. So I'm afraid there is no way to get this format with modern versions of CPLEX.

One obvious fix is to rewrite your application so that it can read XML files as well.

Another option would be to add an intermediate step to convert the XML file into a TXT file that your application can read. This can be done for example using XSLT. Would that work for you? Do you need all fields in the TXT file or only some?

Hi Daniel,

At the end I think that the better option would be to rewrite the application.

Thank you for your help.
