Descripción
A set of vertices W of a graph G is a total k-dominating set when every vertex of G has at least k neighbors in W. In a recent article, Chiarelli et al. (2019) prove that a total k-dominating set can be computed in O(n3k) time when G is a proper interval graph with n vertices and m edges. In this note we reduce the time complexity to O(m) for k=2.
