Advanced sampler modeling the efficiency function as a family of Gaussian processes (with integrated kernel parameters) and sampling from it trying to maximize Expected Improvement.
Variation of the GP optimizer which asumes there is a noise in the evaluations.
Variation of the GP optimizer which asumes there is a noise in the evaluations. The noise might be introduced by instabilities of the learning process for complex non-convex models (eg. neural networks).
Simple sampler from the Sobol points sequence
