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.

G : graph
A Networkx graph.
k : int
A positive integer.
minDominatingSet : list
A smallest dominating set in the graph.
