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

New Algorithms for Weighted $k$-Domination and Total $k$-Domination Problems in Proper Interval Graphs
Given a positive integer k, a k-dominating set in a graph G is a set of vertices such that every vertex not in the set has at least k neighbors in the set. A total k-dominating set, also known as a k-tuple total dominating set, is a set of vertices such that every vertex of the graph has at least k neighbors in the set. The problems of finding the minimum size of a k-dominating, resp. total k-d...
متن کاملTotal Domination in Interval Graphs Revisited
A set of vertices D is a dominating set of a graph G = (V, E) if every vertex in VD is adjacent to a vertex in D. A set of vertices D is a total-dominating set of a graph G = (V, E) if every vertex in V is adjacent to a vertex in D. The problems of finding a minimum cardinality dominating set or a minimum cardinality totaldominating set are both NP-complete for many classes of graphs [6,2], tho...
متن کاملTotal domination in $K_r$-covered graphs
The inflation $G_{I}$ of a graph $G$ with $n(G)$ vertices and $m(G)$ edges is obtained from $G$ by replacing every vertex of degree $d$ of $G$ by a clique, which is isomorph to the complete graph $K_{d}$, and each edge $(x_{i},x_{j})$ of $G$ is replaced by an edge $(u,v)$ in such a way that $uin X_{i}$, $vin X_{j}$, and two different edges of $G$ are replaced by non-adjacent edges of $G_{I}$. T...
متن کاملNonnegative signed total Roman domination in graphs
Let $G$ be a finite and simple graph with vertex set $V(G)$. A nonnegative signed total Roman dominating function (NNSTRDF) on a graph $G$ is a function $f:V(G)rightarrow{-1, 1, 2}$ satisfying the conditionsthat (i) $sum_{xin N(v)}f(x)ge 0$ for each $vin V(G)$, where $N(v)$ is the open neighborhood of $v$, and (ii) every vertex $u$ for which $f(u...
متن کاملTotal Roman domination subdivision number in graphs
A {em Roman dominating function} on a graph $G$ is a function $f:V(G)rightarrow {0,1,2}$ satisfying the condition that every vertex $u$ for which $f(u)=0$ is adjacent to at least one vertex $v$ for which $f(v)=2$. A {em total Roman dominating function} is a Roman dominating function with the additional property that the subgraph of $G$ induced by the set of all vertices of positive weight has n...
