Show Summary Details


Comparison between the real and simulated settlement distributions allows us to assess the goodness-of-fit between them. Since our agents optimize their locations, this is also a measure of the extent to which the real households optimized their locations, which we call “settlement efficiency.” Settlement efficiency tends to peak at the end of each population cycle, as households were leaving the area. We also develop methods for determining which combinations of parameters maximize the goodness-of-fit as that changes through time. This reveals two distinct settlement regimes, separated at AD 1060.
