摘要
For a fixed positive integer k, a k-hop dominating set D of a graph G = (V, E) is a subset of V such that every vertex x is an element of V is within k-steps from at least one vertex y is an element of D, i. e., d(x, y) <= k. A k-hop dominating set D is said to be minimal if there does not exist any D' subset of D such that D' is a k-hop dominating set of G. A dominating set D is said to be minimum k-hop dominating set, if it is minimal as well as it is k-hop dominating set. In this paper, we present an optimal algorithm to find a minimum k-hop dominating set of interval graphs with n vertices which runs in O(n) time.
