Supplementary material for the bbob-biobj and bbob-biobj-ext test suites


Welcome to the website with supplementary material for the bbob-biobj and bbob-biobj-ext test suites from the COCO (Comparing Continuous Optimizers) platform.

It provides function definitions and visualizations for all 92 bbob-biobj-ext problems introduced in the paper Using Well-Understood Single-Objective Functions in Multiobjective Black-Box Optimization Test Suites by Dimo Brockhoff, Anne Auger, Nikolaus Hansen and Tea TuĊĦar submitted to Evolutionary Computation Journal. It also shows the empirical distribution of angles between the two (estimated) gradients at the best known Pareto set approximations in low dimensions. The postprossed data page shows the postprocessed results from a comparison among three selected algorithms.
