Simulation experiment results. (a) Average square-root growth rate as a function of the experiment number for three different choices of the kernel function (Matern52, Matern32 and square exponential), but with the same upper confidence bound (UCB) based acquisition function. (b) Results for three different choices of the acquisition function (UCB, expected improvement (EI), and maximum probility of improvement (MPI)), but with the same Matern52 kernel. (c) Results for four different values of the parameter \(\kappa \) of the UCB acquisition function with the Matern52 kernel. The dashed horizontal line in each panel represents the theoretical maximum (146.0) of the ground truth model.
