“…For some time there has been a need to create a benchmark which could ultimately be used for multi-objective problems, [2] and [3], with particular emphasis on Pareto optimization. In fact, a multi-criteria design is usually needed in many problems of real-life engineering: from classical applications such as electrical machines [4] and [5] to the newest devices in the micro electro-mechanical systems or nano electro-mechanical systems area [6], the approach in terms of multi-objective optimization is more and more used. Moreover, according to the rationale of the no-free lunch theorem, new algorithms need to be tested on specific issues [7]- [9].…”
