grinpy.invariants.domination.min_dominating_set(G)

Return a smallest dominating set in the graph.

The method to compute the set is brute force except that the subsets searched begin with those whose cardinality is equal to the sub-domination number of the graph, which was defined by Amos et al. and shown to be a tractable lower bound for the k-domination number.

Parameters:
  • G (NetworkX graph) – An undirected graph.
  • k (int) – A positive integer.
Returns:

A list of nodes in a smallest dominating set in the graph.

Return type:

list
