Class PopulationUpdate

Object
PopulationUpdate
public class PopulationUpdate 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.

    • PopulationUpdate

      public PopulationUpdate(IBS ibs)
      Instantiate new population update for use in IBS models.
      Parameters:
      ibs - the model using this player update

  • Method Details

    • setType

      public boolean setType(PopulationUpdate.Type type)
      Sets the population update type.
      Parameters:
      type - the updating type for the population
      Returns:
      true if population update type changed

    • getType

      public PopulationUpdate.Type getType()
      Gets the population update type.
      Returns:
      the population update type

    • isSynchronous

      public boolean isSynchronous()
      Determine whether population update is synchronous.
      Returns:
      true if update is synchronous

    • isMoran

      public boolean isMoran()
      Determine whether population update is a variant of Moran updates. Moran type updates do not require specifying a player update type separately.
      Returns:
      true if update is Moran
