ash_model.paths.shortest_s_walk(h, s, fr=None, to=None, start=None, end=None, weight=False, edge=True)[source]

Compute shortest s-walk(s) considering weight or dual hypergraph.

If edge=True, operates on s-line-graph; otherwise uses dual hypergraph node graph.

Parameters:
  • h (ASH) – ASH instance.

  • s (int) – Minimum overlap size.

  • fr (str | None) – Starting hyperedge ID (node or edge depending).

  • to (str | None) – Ending hyperedge ID.

  • start (int | None) – Start time bound.

  • end (int | None) – End time bound.

  • weight (bool) – Use edge weight attribute ‘w’ if True.

  • edge (bool) – If False, compute on dual hypergraph.

Returns:

Single path list if both fr and to set, else dict mapping.

Return type:

List[str] | Dict[str, List[str]]
