Same answer as [Ipopt's "local" optimum can be very substandard - #5 by odow](https://discourse.julialang.org/t/ipopts-local-optimum-can-be-very-substandard/127217/5)

> Additional question: will it be all right to directly write `g(x)` in the 🍅 line, as it was look like in the Gurobi’s code?

Yes. JuMP uses function tracing to compute the underlying expression.
