kl_connected_subgraph
(G, k, l, low_memory=False, same_as_graph=False)[source]¶ Returns the maximum locally
(k, l)
-connected subgraph ofG
.A graph is locally
(k, l)
-connected if for each edge(u, v)
in the graph there are at leastl
edge-disjoint paths of length at mostk
joiningu
tov
.Parameters: - G (NetworkX graph) – The graph in which to find a maximum locally
(k, l)
-connected subgraph. - k (integer) – The maximum length of paths to consider. A higher number means a looser connectivity requirement.
- l (integer) – The number of edge-disjoint paths. A higher number means a stricter connectivity requirement.
- low_memory (bool) – If this is True, this function uses an algorithm that uses slightly more time but less memory.
- same_as_graph (bool) – If True then return a tuple of the form
(H, is_same)
, whereH
is the maximum locally(k, l)
-connected subgraph andis_same
is a Boolean representing whetherG
is locally(k, l)
-connected (and hence, whetherH
is simply a copy of the input graphG
).
Returns: If
same_as_graph
is True, then this function returns a two-tuple as described above. Otherwise, it returns only the maximum locally(k, l)
-connected subgraph.Return type: NetworkX graph or two-tuple
