| الوصف: | Fokker-Planck approximation for the fixation probabilities and mean-first passage times (MFPTs) for the Moran model (dotted lines) and the spatial exclusion model (solid lines) for various system sizes ( N = 10, 100, 1000). (A) The fixation probability in the spatial model is sigmoidal around an inflection point at f = 1/2 and becomes increasingly steep, approaching a step-function at large N . The Moran model, in contrast, always predicts a linear fixation probability equal to the fractional abundance. (B) For the spatial exclusion model, the MFPTs at varying N collapse onto each other for most fractional abundances except around the inflection point. The dynamics away from f = 1/2 follow a deterministic path to fixation approximated by τ det (dashed red line) from Eq 7 . Notably, the MFPTs in the spatial model are significantly faster than those predicted by the Moran model. (C) The maximal MFPT of the Moran model is linear in N whereas the maximal MFPT of the spatial model grows substantially slower and sub-linear in N ; see Fig 3C . |
