Among other important issues of Model-based Optimization, the article deals with methods for discrete or combinatorial optimization problems. A tabular survey of works in this field is part of the supplementary material. A PDF of this table will be kept up-to-date on this website, see:
Survey: Combinatorial Surrogate Models
