Approximate unnormalized posterior density (2D and 1D slices) near the optimum value (f dur 220 ms, d sel 290 ms, p rec 0.58) using approximate Bayesian computation and 560 CPU‐hours of computation (420 model evaluations, 28 h of wall‐clock time). The ABC threshold ε was 7.45, which is 0.01 above the estimated minimum of the Gaussian process surrogate. The color map is such that black is 0.0 and white is 0.2; lighter shades indicate higher posterior probability.
