hiperwalk.Multigraph.vertex_number#
- Multigraph.vertex_number(vertex)#
Return the numerical label of a vertex based on its representation.
This method is designed to handle graphs where vertices might have multiple representations, such as coordinates in a grid. In cases of arbitrary graphs, this function will return the input itself if it is a valid representation.
- Parameters:
- vertexint
The vertex in any valid representation. For arbitrary graphs, only the vertex’s label is accepted.
- Returns:
- int
The numerical label of the vertex.
- Raises:
- ValueError
If the
vertex
is not a valid representation.
Notes
Implementing this function is beneficial for arbitrary graphs as it simplifies the implementation of some quantum walk methods.
