public class UndirectedTriplesHistogram
extends ModelShell
implements Algorithm

Rediscovery of Batagel-Mrvar algorithm Batagel, V., A. Mrvar. 2001. A subquadratic triad census algorithm for large sparse networks with small maximum degree. Social Networks 23:237-43. Transforms a graph object (one mode and relation) into 4 dimensional double array describing a histogram of all triples of actors in the graph.
Links are classified in the following way:

• 0: no link exists
• 1: smaller->greater link exists
• 2: greater->smaller link exists
• 3: bi-directional link exists

Method Detail

execute

public void execute(Graph g)

Description copied from interface: Algorithm

execute the algorithm against the given graph

Specified by:

execute in interface Algorithm

Parameters:

g - graph to be modified

getLinks

protected java.util.TreeSet<Actor> getLinks(Graph g,
                                            java.util.LinkedList<Actor> v,
                                            java.util.LinkedList<Actor> comparator,
                                            java.util.TreeSet<Actor> allNeighbors)

getInputType

public java.util.List<IODescriptor> getInputType()

Description copied from interface: Component

The input type describes all the different kinds of graph objects that are utilized (and hence required) by this object. This result is only guaranteed to be fixed if structural parameters are not modified. This is an empty array if there is no input.

Specified by:

getInputType in interface Component

Returns:

IODescriptor array for this component

See Also:

IODescriptor

getOutputType

public java.util.List<IODescriptor> getOutputType()

Description copied from interface: Component

The output type describes all the different kinds of graph objects that are created during the execution of this algorithm. The result is only guaranteed to be fixed if structural parameters are not modified. This is an empty array if there is no output.

Specified by:

getOutputType in interface Component

Returns:

IODescriptor array for this component

See Also:

IODescriptor

getParameter

public Properties getParameter()

Description copied from interface: Component

List of all parameters this component accepts. Each parameter also has a distinct key-name used when initializing the object using the init method. If there are no parameters, null is returned.

Specified by:

getParameter in interface Component

Returns:

read-only array of Parameters

getParameter

public Parameter getParameter(java.lang.String param)

Description copied from interface: Component

Returns the specific parameter identified by its key-name. If no parameter is found with this key-name, null is returned.

Specified by:

getParameter in interface Component

Parameters:

param - key-name of the parameter

Returns:

named parameter

init

public void init(Properties map)

Parameters:

• name: name of this algorithm. Default is 'Graph Undirected Triples Histogram'
• actorType: mode of actor to execute over. Default is 'tag'
• relation: link relation to execute over. Default is 'Tags'
• propertyNameSuffix: Property ID suffix for the graph property. Deafult is ' Undirected Triples Histogram'

Specified by:

init in interface Component

Parameters:

map - parameters to be loaded - may be null

prototype

public UndirectedTriplesHistogram prototype()

Description copied from interface: Component

All Components implement the prototype pattern. The new parameter has no common resources to the original that are not static resources o the class.

Specified by:

prototype in interface Component

Specified by:

prototype in interface Algorithm

Returns:

default-parameter version of the same class as the original.
