This paper presents a very simple surrogate optimization method -a Tolerance-based Surrogate Method. A surrogate optimization in general is essential to more and more frequently used optimization in the development process of new technologies. Fitness functions of such systems are often costly, therefore keeping a number of evaluations of the fitness functions at minimum is of a great importance in order to save computer and time resources, i.e. the overall cost of design. Unlike other complex surrogate optimization methods, the tolerance-based surrogate method does not require excessive computational resources, is easy to implement, and is flexible for all types of optimization algorithms. Behaviour of the tolerance-based surrogate method is demonstrated on several modified benchmark problems. Afterwards, our method is verified on a real-world time-demanding optimization task.

“…The paper [13] presents the comparison of the performance of two algorithms, GDE3 and NSGA-II, in design of the band-stop filter. Both algorithms had 20 agents over 20 iterations, which means that each algorithm needed 400 fitness function evaluations.…”
