Estimation of distribution algorithms (EDAs) have become promising kinds of evolutionary algorithms. They are based on sampling an estimated distribution of the better of the solutions from the last generation -- iteration of the algorithm.
Learning the distribution and sampling is used instead of reproduction common in traditional evolutionary algorithms. In many real-world optimization tasks, objective-function-evaluation of any solution is very expensive, so the lowest possible number of such evaluations is desired.
We propose using surrogate models in combination with EDAs as a method of reducing the evaluation costs.
