Each of the Sobol' point optimisations can be performed completely independently and run simultaneously across high performance computing clusters. At termination, the optimal value of the total merit function and the associated parameters are reported as the solution obtained from each Sobol' seed used to generate p[0] . Post-analysis of the results is carried out by comparison of the optimal total merit function values and solutions are clustered into distinct minima. The parameter values which produce the lowest total merit function can then be selected as the optimal parameter set.
