(G, weight='weight', default_weight=1)[source]¶ Returns the longest path in a directed acyclic graph (DAG).
If
G
has edges withweight
attribute the edge data are used as weight values.- Parameters
G (NetworkX DiGraph) – A directed acyclic graph (DAG)
weight (str, optional) – Edge data key to use for weight
default_weight (int, optional) – The weight of edges that do not have a weight attribute
- Returns
Longest path
- Return type
list
- Raises
NetworkXNotImplemented – If
