Population update
Determines the update type of the population. This is strongly related to the underlying biological/sociological scenario.
synchronous
Players interact and update their strategic behavior in a synchronized fashion. This refers to situations where external influences such as diurnal rhythms or seasonal changes lead to a synchronization of e.g. the breeding season or competitive interactions such as under harsh environmental conditions occurring in the arctic.
asynchronous - replicate
Under more favorable climatic conditions animals may breed and reproduce throughout the year. This is modeled with asynchronous population updates. Players that interact and reassess their strategies are chosen at random. This represents and approximation to continuous time models.

Population size
Specifies the number of individuals in the population. Note that certain geometries add some constraints on the population size, e.g. a hexagonal lattice requires squared even integer number. In case the requirements are not satisfied, the population size will be reduced as appropriate.
