    Hello,
    I really tried to find an example for this but have not been successful. I have a MIP problem and would like to provide CPLEX with a starting solution. I am using IBM ILOG CPLEX Optimization Studio 12.7.

    This can't be too difficult. Could someone please post an example (or point me to one) how to provide CPLEX the starting solution for a problem and data format it has to be in (as well as how I create it). I feel there are many resources when using Java or C++ but limited when using the ILOG Optimization Studio interface.

    Much appreciated!

     

    Thanks,

    Michael

    The "warmstart" example (warmstart.mod in opl/examples/opl/warmstart) illustrates how to do that. This is also described in the user manual here.
