Convergence time τc associated with SMD (red squares), MetaD (blue circles), and d-MetaD (black triangles) simulations performed on polyproline peptides of length n = 1, ..., 5. The data were fitted using a τc = reαn function (linear fitting in the (log τc,n) space). Inset: τc associated with the d-MetaD method fitted using a linear function τc = an.
