That's good to hear. I don't have any other specific requests - for me it seems impossible to know what will work on my problems, so i just try things at random to see what works!

I don't know the architecture of your project, but is there any way it could include NLopt, and so make all of its algorithms available? Some of them could be useful, and i doubt it's a good use of your time to reimplement them all from scratch.

Unfortunately NLopt cannot be included into Gradient-Free-Optimizers. But i would like to implement multiple algorithms that are also preset in NLopt.

I think it will help my understanding of optimization algorithms if i implement them myself. I currently have my eyes on the Downhill-simplex, Direct and Powell's Method. But they are quite different from what i have already implemented, so this could take some time.
