Data description: we benchmarked 800 different hybridizations of the Particle Swarm Optimization (PSO) and Differential Evolution (DE) algorithms on a well-known continuous black-box problem set called COCO/BBOB, which consists of 24 test functions. 30 independent runs are conducted for each algorithm on each problem.

• 'ERT.csv': a data frame with columns DIM (5D or 20D), funcId (F1-24), algId (algorithm names), target (\(10^{\{-8,-7, \ldots, 1\}}\)), ERT (expected running time), and sd (standard deviation).
• 'raw-data.csv': the running time recorded in each independent run. 
• 'analysis.R': the R script that generates ERT tables in the paper.
• 'ecdf.R': the R script that renders the ECDF (empirical cumulative distribution function) plots in the paper.
