Decision Optimization

Hello,

I have a C# project that calls a CPLEX model using a .MOD/.DAT file. The .DAT file is populated using a custom OPL Data source derived from ILOG.OPL.CustomOplDataSource. 

I need to convert this to a C++ solution and I would like to still use the same approach, i.e. .MOD plus data.

Google'ing CPLEX C++ .MOD does not turn up any useful information.

Please can someone point me to the C++ classes which are the equivalent (or close enough) to the C# classes that are used to read .MOD files and interact with .DAT files.

Kind regards,

Mark

You should look at the opl/examples/opl_interfaces/cpp/src/oplrunsample.cpp example shipped with CPLEX Optimization Studio. This illustrates how to load .mod and .dat files and run projects.

There also is example opl/examples/opl_interfaces/cpp/src/customdatasource.cpp that illustrates custom data sources in C++.
