public class VoterExperiment
extends Experiment
implements java.io.Serializable

This class models the voter experiment. Each member of a rectangular lattice of voters can, at any time, be in one of a finite number of states, represented by colors. At each time, a voter is chosen at random and then a neighbor of the voter is chosen with various probabilities. The state of the chosen voter is then changed to the state of the chosen neighbor.

Method Detail

init

public void init()

This method initializes the experiment, including the set of voters, the toolbar with choices and labels.

Overrides:

init in class Experiment

getAppletInfo

public java.lang.String getAppletInfo()

This method returns basic information about the applet, including copyright information, descriptive information, and instructions.

Specified by:

getAppletInfo in interface IExperiment

Overrides:

getAppletInfo in class Experiment

Returns:

applet information

doExperiment

public void doExperiment()

This method defines the experiment. A voter is chosen at random and then a neighbor of the voter is chosen according to specified probabilities. The state of the voter is changed to the state of the neighbor. The stop condition is tested.

Specified by:

doExperiment in interface IExperiment

Overrides:

doExperiment in class Experiment

step

public void step()

This method runs the experiment one time, playing a note that depends on the new state of the voter.

Specified by:

step in interface IExperiment

Overrides:

step in class Experiment

reset

public void reset()

This method resets the experiment, including the voters, and the record table.

Specified by:

reset in interface IExperiment

Overrides:

reset in class Experiment

update

public void update()

This method updates the display, including the voters and the record table.

Specified by:

update in interface IExperiment

Overrides:

update in class Experiment

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent e)

This method handles the events associated with the stop choice and the voter choice.

Specified by:

Overrides:

itemStateChanged in class Experiment

Parameters:

e - the item event

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

This method handles the mouse events that correspond to clicking on a voter. The state of the voter is changed to the edit state, and the record table is updated.

mouseClicked in interface java.awt.event.MouseListener

Overrides:

mouseClicked in class Experiment

Parameters:

e - the mouse event

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

This method handles the events for the probability button. The neighbor probabilities are passed to the probability dialog box which is then displayed. If the user clicks OK, the new probabilities are passed to the voter array.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

actionPerformed in class Experiment

Parameters:

e - the action event

getResultTable

public javax.swing.JTable getResultTable()

Specified by:
