IFLAG - Messages
MIDACO returns specific warning and error messages via an information flag value called IFLAG. In case of warnings, the IFLAG value is printed on the screen and MIDACO will proceed with the optimization nevertheless. In case of errors, MIDACO will stop immediately, displaying the IFLAG value on the screen. In the regular case (no warning or error) MIDACO will provide a final IFLAG message along with the solution, indicating the stopping criteria and the feasibility. Here a complete list of IFLAG messages by MIDACO is given.
