public class CycleBasis
extends Object

A minimum basis of all cycles in a graph. All cycles in a graph G can be constructed from the basis cycles by binary addition of their invidence vectors. A minimum cycle basis is a Matroid.

Constructor Detail

CycleBasis

public CycleBasis(org._3pq.jgrapht.UndirectedGraph g)

Deprecated.

Constructs a minimum cycle basis of a graph.

Parameters:

g - the graph for the cycle basis

Method Detail

weightVector

public int[] weightVector()

Deprecated.

cycles

public Collection cycles()

Deprecated.

Returns the cycles that form the cycle basis.

Returns:

a Collection of the basis cycles

essentialCycles

public Collection essentialCycles()

Deprecated.

Returns the essential cycles of this cycle basis. A essential cycle is contained in every minimum cycle basis of a graph.

Returns:

a Collection of the essential cycles

relevantCycles

public Map relevantCycles()

Deprecated.

Returns the essential cycles of this cycle basis. A relevant cycle is contained in some minimum cycle basis of a graph.

Returns:

a Map mapping each relevant cycles to the corresponding basis cycle in this basis

equivalenceClasses

public List equivalenceClasses()

Deprecated.

Returns the connected components of this cycle basis, in regard to matroid theory. Two cycles belong to the same commected component if there is a circuit (a minimal dependent set) containing both cycles.

Returns:

a List of Sets consisting of the cycles in a equivalence class.
