Return a smallest k-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-k-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.
- G (NetworkX graph) – An undirected graph.
- k (int) – A positive integer.
A list of nodes in a smallest k-dominating set in the graph.
