    I am calling cplex from C# to solve an LP Problem. After running, I am getting this error message: 

    Infeasible column 'X_30'

     

    That does not tell me much about which constraints are having a conflict and why there is an infeasibility.

     

    After doing some Research, I am seeing that some people are using a 'Conflict Report/ Conflict Refiner'. How can you get this report, is there a call from C# that I can use?

    Yes, there is Cplex.RefineConflict(). See also the description of the conflict refiner in the user manual.

    Thanks, so where do I call this method Cplex.RefineConflict()? Right after I write the Model to an LP file  cplex.ExportModel("MyLPModel.lp")  or is it after I call cplex.Solve()?

    And if so, how do I look at the result? Can you give me a simple illustrative example where RefineConflict() is used with C#?

    Can you please take a look at this section in the user manual? It describes how to use the conflict refiner in C++ but C# should be completely analogous.
