To find the strengths and weaknesses of a new multi-objective optimization algorithm, we need to compare its performance with the performances of the state-of-the-art algorithms. Such a comparison involves a selection of a performance metric, a set of benchmark problems, and a statistical test to ensure that the results are statistical significant. There are also studies in which instead of using one performance metric, a comparison is made using a set of performance metrics. All these studies assume that all involved performance metrics are equal. In this paper, we introduce a data-driven preference-based approach that is a combination of multiple criteria decision analysis with deep statistical rankings. The approach ranks the algorithms for each benchmark problem using the preference (the influence) of each performance metric that is estimated using its entropy. Experimental results show that this approach achieved similar rankings to a previously proposed method, which is based on the idea of the majority vote, where all performance metrics are assumed equal. However, as it will be shown, this approach can give different rankings because it is based not only on the idea of counting wins, but also includes information about the influence of each performance metric.
