Examples of the algorithms’ solutions in the 2Dim parameter space. All plots illustrate the outcome for the same subject. As indicated in the legends, the results of the 2Dim parameter optimizations via NMA (NMA2D), PSO (PSO2D), CMAES (CMAES2D) and BO (BO2D) are visualized by colored symbols (diamonds, squares, triangles and circles, respectively). For each method, 15 optimal parameter points obtained from 15 algorithm executions with random initial conditions are indicated. The background fill of the plots illustrates the shape of the parameter space as discovered by the grid search, see also Fig. S1. It shows the similarity (Pearson correlation) between simulated and empirical FC on a color scale reaching from dark blue (low similarity) to dark red (high similarity). The figure was created with MATLAB R2018a (www.mathworks.com).
