The convergence of the algorithm for all test problems across 128 Sobol' point optimisations can be found in Table of the supporting information. The behaviour of the algorithm appears to be broadly equivalent to the point-charge model. A slightly higher proportion of algorithmic failures and convergence to sub-optimal solutions is observed, although the difference is not significant. Roughly the same number of unique minima are identified as before, ranging between 1 and 3 minima found per test problem. We also find that convergence to a locally minimum point does not guarantee that the very best solution has been found. In fact, for TP6 and TP7, many of the points that did not converge to a locally minimum point achieve lower objective function values than any of the local minima identified.
