Sigmoid functions are used in many fields of scientific life for the description of several phenomena. Comparing several sigmoid type curves, in this paper useful functions are selected which can be used during the evaluation and qualification process of teams and their results. On the basis of the analysis of the characteristics of these curves and their derivatives and integral curves, a system of 38 points of view is proposed as a possible new comparison system (EBSYQ) for ranking, comparing or evaluating the results of groups. Using this system it will be easier to decide the winning team or the best achivement among several groups, even in case of difficult or complicated decision- making situations. The working and efficiency of the proposed system is shown by the example of the comparison process of two groups of students studying the same course. The proposed evolutionary based system of evaluation could be used not only for student groups, but also for sport results or for the comparison and analysis of evolutionary type optimisation algorithms.
