• [x] Adapt plot such that points smaller than 0 are not removed.
• [x] \hat y_i predicted target based on surrogate ...
• [x] "The calculation considers for each iteration the predicted target ..." What does this mean? Can you be more precise here?
• [x] "If R^2 is low: the surrogate model might be not suitable for the problem; thus, another surrogate model class might be taken into account to improve the quality of the surrogate fit and thus the overall optimization result"
