Looks very nice!
Two questions off top of my head:
- Might be worth mentioning how Hyperactive compares to tons of other similar packages, like Hyperopt, Optunity and a ton of others? Also how your GFO package is different from optima, opytimizer, and many others as well. Having some benchmarks or performance stats (or even just listing functionality differences) would be very helpful to anyone who's been already using those.
- One of the best universal 'works-out-of-the-box-most-of-time' global optimizers I've used recently is DLib's: http://blog.dlib.net/2017/12/a-global-optimization-algorithm... - any chances for implementing something similar?
