maximal_independent_set(G, nodes=None, seed=None)¶
Returns a random maximal independent set guaranteed to contain a given set of nodes.
An independent set is a set of nodes such that the subgraph of G induced by these nodes contains no edges. A maximal independent set is an independent set such that it is not possible to add a new node and still get an independent set.
G (NetworkX graph)
nodes (list or iterable) – Nodes that must be part of the independent set. This set of nodes must be independent.
seed (integer, random_state, or None (default)) – Indicator of random number generation state. See Randomness.
indep_nodes – List of nodes that are part of a maximal independent set.
- Return type
>>> G = nx.path_graph(5) >>> nx.maximal_independent_set(G) [4, 0, 2] >>> nx.maximal_independent_set(G, ) [1, 3]
This algorithm does not solve the maximum independent set problem.
