Photo: Because the sphere function can be solved fast, more than 67% of all target values coincide with the final target value 1e-8 (the target values are based on the run lengths of the respective BBOB-2009 best algorithm). The second difficult target value is 39.8107171 and reached by all methods. The results suggest a limitation when using run-length based targets if the function can "be solved" within very few evaluations by the best algorithm.Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo: Photo:
