@Deprecated
public abstract class EulerianCircuit
extends java.lang.Object

This algorithm will check whether a graph is Eulerian (hence it contains an Eulerian circuit). Also, if a graph is Eulerian, the caller can obtain a list of vertices making up the Eulerian circuit. An Eulerian circuit is a circuit which traverses each edge exactly once.

Method Detail

isEulerian

public static <V,E> boolean isEulerian(UndirectedGraph<V,E> graph)

Deprecated.

Test whether a graph is Eulerian. An undirected graph is Eulerian if it is connected and each vertex has an even degree.

Type Parameters:

V - the graph vertex type

E - the graph edge type

Parameters:

graph - the input graph

Returns:

true if the graph is Eulerian, false otherwise

getEulerianCircuitVertices

public static <V,E> java.util.List<V> getEulerianCircuitVertices(UndirectedGraph<V,E> g)

Deprecated.

This method will return a list of vertices which represents the Eulerian circuit of the graph.

Type Parameters:

V - the graph vertex type

E - the graph edge type

Parameters:

g - The graph to find an Eulerian circuit

Returns:

null if no Eulerian circuit exists, or a list of vertices representing the Eulerian circuit if one does exist
