Class SpeciesUpdate

Object
SpeciesUpdate
public class SpeciesUpdate extends Object
The implementation of population updates. Population updates are used to update the population size and composition of individuals.

The population update type can be set to one of the following:

synchronous
Synchronized population updates.
Wright-Fisher
Wright-Fisher process (synchronous)
asynchronous
Asynchronous population updates (default).
Bd
Moran process (birth-death, asynchronous).
dB
Moran process (death-birth, asynchronous).
imitate
Moran process (imitate, asynchronous).
ecology
Asynchronous updates (non-constant population size).

The population update type can be set via the command line option --popupdate <u> [<p>] where <u> is the population update type, and <p> the fraction of individuals that reassess their strategy.

    Description
    static enum 
    SpeciesUpdate.Type
    Types of species updates (only relevant for multi-species models): size focal species selected proportional to their size fitness focal species selected proportional to their total fitness turns one species is selected after another. sync simultaneous updates of all species (not yet implemented). For size and fitness selection is also proportional to the update rate of each species.
