摘要

Dynamic of population growth on two-dimensional lattice N_x x N_y = 1000 x 1000 is simulated with rules that involve interaction between neighbours. Biological aging is described by a systematic decrease with each time step of parameter g(i), a measure of the health condition for each individual i. When g drops down below a minimum value, the death of the item occurs. The death toll is also caused by the Verhulst factor which accounts for the limited living space. Newly borns inherit g from parent's, plus some extra value to help them to start the life game. This basic rule is enriched by (a) some corrections of the parameter g(i) according to its current values among the nearest and next nearest neighbours, and/or (b) the possible limitation of newborns to be placed in the close neighbourhood of parents. We discuss influence of the birth rate on the size of the final population and its age distributions, then g-g correlations c of the health condition g on the nearest neighbours. Main conclusion is that interaction between neighbours may play important role modifying the population characteristics, also the restrictions on whether the babies are bound to stay with parents or not yield different results.
