WebJan 27, 2024 · (2) GradObj='off' was intentional, but DerivativeCheck='on' was unintentional. If so, it would be your wish that the optimization proceed without a derivative check and, indeed, that is what happens. That said, I do agree that an explicit warning message in case (1) would be more aesthetic.
