   - [ ] add Ant-colony optimization
   - [ ] add Harmonic-serch
-  - [ ] add Differential evolution
   - [ ] add API, testing and doc to (better) use GFO as backend-optimization package
   - [ ] add Random search parameter that enables to avoid replacement of the sampling
   - [ ] add other acquisition functions to smbo (Probability of improvement, Entropy search, ...)
