Actually this is only a dummy example to isolated the issue I have with the problem I want to optimize. In the complete optimization I use a [two-point estimation](https://en.wikipedia.org/wiki/Numerical_differentiation) for...

A more complete code example using numerical two point differentiation for gradient calculation and a equality constraint that is always respected (always 0.0). - Works without the equality constraint -...
