Empirical cumulative distributions (ECDF) of run lengths and speed-up ratios in 5-D (left) and 20-D (right). Left sub-columns: ECDF of the number of f-evaluations divided by dimension D (FEvals/D) to reach a target value Iref+∆I with ∆I =10k, where k is given by the first value in the legend, for algorithmA (°) and algorithmB () . Right sub-columns: ECDF of FEvals ratios of algorithmA divided by algorithmB for fixed target precision values 10k with k given in the legend; all trial pairs for each function. Pairs where both trials failed are disregarded, pairs where one trial failed are visible in the limits being > 0 or < 1. The legend also indicates, after the colon, the number of functions that were solved in at least one trial (algorithmA first).
