  • 1.  cannot find the conflict in model

    I met conflict in my model, and then I input this problem, but I cannot find the conflict in my model, because I don't understand the "\Sum of equality rows in the conflict:" meaning, and in my model, I don't have this constraint.

    so can some one to help me, tell me the reason in my model?

    thanks

    As you can see, the line "\Sum of equality rows ..." starts with a backslash. That is the comment character in LP format, so the line can be ignored.

    Your model does not contain this constraint. This row just specifies the sum of the equality constraints because sometimes this sheds a little more light on the actual conflict. You can ignore this row and just look at the rest of the conflict.
