In benchmarking theory, creating a comprehensive and uniformly distributed set of problems is a crucial first step to designing a good benchmark. However, this step is also one of the hardest, as it can be difficult to determine how to evaluate the quality of the chosen problem set.

In this article, we evaluate if the field of exploratory landscape analysis can be used to develop a generalized method of visualizing a set of arbitrary optimization functions. We present a method for visually determining the distribution of problems within a benchmark set using exploratory landscape analysis combined with clustering and t-sne visualization, and evaluate and explain the visualization this methodology produces.

The proposed method is evaluated on a set of benchmark problems taken from two well known state-of-the-art real-parameter single objective optimization benchmarks: the CEC Special Sessions and Competitions on …
