一个图G =(V,E)的t-规则集是一个独立的顶点子集S ∈ V,它满足这样的性质:每个顶点v ∈ V与S中的某个顶点的距离不超过t跳。极大独立集(MIS)是一个1-规则集。本文扩展了Kothapalli et al.(FSTTCS 2012)的结果,提出了一个随机算法,用于以高概率计算t-规则集,在2 < t ≤ n(log log n)时,时间复杂度为O(t log 1/(t-1)n),在t > n(log log n)时,时间复杂度为O(t(log log n))。
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).
