public class JinGirNewModelII
extends SimModelImpl

This is an implementation of the second model (model II) described in Jin, Girvan, and Newman, "The Structure of Growing Social Networks." Santa Fe Institute 2001 working paper. This paper can be found on-line at http://www.santafe.edu/sfi/publications/Abstracts/01-06-032abs.html

Their abstract follows:

"We propose some simple models of the growth of social networks, based on three general principles: (1) meetings take place between pairs of individuals at a rate which is high if a pair has one or more mutual friends and low otherwise; (2) acquaintances between pairs of individuals who rarely meet decay over time; (3) there is an upper limit on the number of friendships an individual can maintain. using computer simulations, we find that models that incorporatge all of these features reproduce many of the features of real social networks, including high levels of clustering or network transitivity and strong community structure in which individuals have more links to others within their community than to individuals from other communities."

See the repast/demo/jinGirNew/readme for details on the parameters of this model.

begin

public void begin()

Description copied from interface: SimModel

Begins a simulation run. All initialization, building the model, diplay, etc. should take place here. This method is called whenever the start button (or the step button if the run has not yet begun) is clicked. If running in batch mode this is called to kick off a new simulation run.

setup

public void setup()

Description copied from interface: SimModel

Prepares a model for a new run, typically by deallocating objects or setting them to some reasonable default. Called whenever the setup button is clicked or if operating in batch mode whenever a single run has ended in preparation for the next. Also called when the model is first loaded.

getInitParam

public java.lang.String[] getInitParam()

Description copied from interface: SimModel

Gets the names of the initial model parameters to set. These names must have get and set methods supplied by the model. For example, for the parameter maxAge, the model must have getMaxAge and setMaxAge methods.

Returns:

a String[] of the initial parameter names

getSchedule

public Schedule getSchedule()

Description copied from interface: SimModel

Gets the Schedule created by the model.

Returns:

the schedule created by the model

getName

public java.lang.String getName()

Description copied from interface: SimModel

Gets the name of the model/simulation.

Returns:

the name of the model/simulation

main

public static void main(java.lang.String[] args)
