BarabasiAlbertGeometry

public BarabasiAlbertGeometry(EvoLudo engine)

Create a Barabási-Albert geometry tied to the given engine.

Parameters:

engine - EvoLudo pacemaker

Method Details

parse

public boolean parse(String arg)

Description copied from class: AbstractGeometry

Parse geometry-specific CLI options.

Overrides:

parse in class AbstractGeometry

Parameters:

arg - the argument string without the geometry key

Returns:

true if parsing succeeded, false if invalid

init

public void init()

Generates a connected undirected scale-free network following the Barabási–Albert preferential attachment model.

Specified by:

init in class AbstractGeometry

pickPreferentialNode

private int pickPreferentialNode(int n,
 int ndice)

Picks a node according to preferential attachment.

Parameters:

n - current node index

ndice - random index for selection

Returns:

selected node index
