Method Detail

getCycles

public Set<List<E>> getCycles()

Return the set of cycles of the cycle basis.

Specified by:

getCycles in interface CycleBasisAlgorithm.CycleBasis<V,E>

Returns:

the set of cycles of the cycle basis

getLength

public int getLength()

Get the length of the cycle basis. The length of the cycle basis is the sum of the lengths of its cycles. The length of a cycle is the total number of edges of the cycle.

Specified by:

getLength in interface CycleBasisAlgorithm.CycleBasis<V,E>

Returns:

the length of the cycles basis

getWeight

public double getWeight()

Get the weight of the cycle basis. The weight of the cycle basis is the sum of the weights of its cycles. The weight of a cycle is the sum of the weights of its edges.

Specified by:

getWeight in interface CycleBasisAlgorithm.CycleBasis<V,E>

Returns:

the length of the cycles basis

getCyclesAsGraphPaths

public Set<GraphPath<V,E>> getCyclesAsGraphPaths()

Return the set of cycles of the cycle basis.

Specified by:

getCyclesAsGraphPaths in interface CycleBasisAlgorithm.CycleBasis<V,E>

Returns:

the set of cycles of the cycle basis
