Is the Nelder-Mead a.k.a. the other simplex method any good? I remember most of these other methods from my optimisation lessons, but I'm surprised to not see Nelder-Mead in this list.
If there are more "must have"-algorithms you could open an issue in Gradient-Free-Optimizers.
I don't know if it's popular, heheh, it's been a while since I've been in maths school, so that's why I'm asking.
