Further Information

Dai, Li, and Wu proposed Rule k, a localized approximation algorithm that attempts to find a small connected dominating set in a graph. In this paper we consider the average-case performance of two closely related versions of Rule k for the model of random unit disk graphs constructed from n random points in an ℓn x ℓn square. We show that if k ≥ 3 and ℓn = o(n), then for both versions of Rule k, the expected size of the Rule k dominating set is Θ(ℓ2n) as n → ∞. It follows that, for ℓn in a suitable range, the expected size of the Rule k dominating sets are within a constant factor of the optimum.
