xgi.algorithms.shortest_path

Algorithms for computing shortest paths in a hypergraph.

Functions

xgi.algorithms.shortest_path.single_source_shortest_path_length(H, source)

Returns the distances from source to every other node in hypergraph H.

Parameters:

• H (xgi.Hypergraph) – Hypergraph on which to compute the distances. Node indexes must be integers.

• source (int) – Index of the node from which to compute the distance to every other node.

Returns:

dists – Dictionary where keys are node indexes and values are the distances from source.

Return type:

dict

xgi.algorithms.shortest_path.shortest_path_length(H)

Returns a generator of tuples (source, dists) where dists is a dictonary containing the distances from source to every other node in hypergraph H, for all possible source in H.

Parameters:

H (xgi.Hypergraph) – Hypergraph on which to compute the distances. Node indexes must be integers.

Returns:

paths – Every tuple is of the form (source, dict_of_lengths), for every possible source.

Return type:

generator of tuples
