A t-ruling set of a graph G = (V, E) is a vertex-subset S ⊆ V that is independent and satisfies the property that every vertex v ∈ V is at a distance of at most t hops from some vertex in S. A maximal independent set (MIS) is a 1-ruling set. Extending results from Kothapalli et al. (FSTTCS 2012) this note presents a randomized algorithm for computing, with high probability, a t-ruling set in O(t ⋅ log1/(t-1)n) rounds for 2 < t ≤ √(log log n) and in (O(√(log log n))) rounds for t > √(log log n).
