where θ + i and θ - i are used to abbreviate θ y tol i -y i and θ y i -y tol i , respectively. We set the smoothing parameter τ = 0.001 in all our experiments. S.6. PLOTTING AND ANALYSIS TABLE . Supported plot types in Olympus' plotting module. n indicates that the plot type supports an arbitrary number of parameters or objectives. † produces a separate trace subplot for each objective. ‡ produces a scatter plot of all objective measurements with the Pareto optimal values indicated, as well as a visualization of the Pareto front. The pareto front plot supports only one optimization campaign with one experiment planning strategy at a time.
