Inhomogeneity reduces memory capacity. a The maximum retrievable sequence length is shown (colored discs) as a function of the number P of associations stored in the network and the corresponding mean connectivity c. Different colors indicate inhomogeneities (${\sigma }_{\varphi }/{\varphi }_0$). b Power law fits to the decreasing parts of the graphs in a give rise to a cutoff capacity $P_c$ (top) at which the curves start to fall, and an exponent α (negative slopes in a) of the power law decrease. Parameters were $N={10}^5$, $c_m=0.1$, and ${\varphi }_0=0.01$
