Abstract:
Let G = (V (G), E(G)) be an undirected graph with γ(C) ̸= 1 for each component C of G. Let S = (v1, v2, · · · , vk) be a sequence of distint vertices of a graph G, and let Sˆ ={v1, v2, . . . , vk}. Then S is a legal open hop neighborhood sequence if N2G(vi) \Si−1j=1 N2G(vj ) ̸= ∅for every i ∈ {2, . . . , k}. If, in addition, Sˆ is a total hop dominating set of G, then S is a Grundy total hop dominating sequence. The maximum length of a Grundy total hop dominating sequence in a graph G, denoted by γth gr(G), is the Grundy total hop domination number of G. In this paper, we show that the Grundy total hop domination number of a graph G is between the total hop domination number and twice the Grundy hop domination number of G. Moreover, determine values or bounds of the Grundy total hop domination number of some graphs.

Abstract:
Domination problems are fundamental problems in graph theory with diverse applications in optimization, network design, and computational complexity. This paper investigates {k}-domination, k-tuple domination, and their total domination variants in weighted strongly chordal graphs and chordal bipartite graphs. Specifically, the {k}-domination problem in weighted strongly chordal graphs and the total {k}-domination problem in weighted chordal bipartite graphs are shown to be solvable in O(n+m) time. For weighted proper interval graphs and convex bipartite graphs, we solve the k-tuple domination and total k-tuple domination problems in O(n2.371552log2(n)log(n/δ)), where δ is the desired accuracy. Furthermore, for weighted unit interval graphs, the k-tuple domination problem achieves a significant complexity improvement, reduced from O(nk+2) to O(n2.371552log2(n)log(n/δ)). These results are achieved through a combination of linear and integer programming techniques, complemented by totally balanced matrices, totally unimodular matrices, and graph-specific matrix representations such as neighborhood and closed neighborhood matrices.

Abstract:
If $G$ is a graph with vertex set $V(G)$, then let $N[u]$ be the closed neighborhood of the vertex $u\in V(G)$. A total double Italian dominating function (TDIDF) on a graph $G$ is a function $f:V(G)\rightarrow\{0,1,2,3\}$ satisfying (i) $f(N[u])\ge 3$ for every vertex $u\in V(G)$ with $f(u)\in\{0,1\}$ and (ii) the subgraph induced by the vertices with a non-zero label has no isolated vertices. A TDIDF is an outer-independent total double Italian dominating function (OITDIDF) on $G$ if the set of vertices labeled $0$ induces an edgeless subgraph. The weight of an OITDIDF is the sum of its function values over all vertices, and the outer independent total double Italian domination number $\gamma_{tdI}^{oi}(G)$ is the minimum weight of an OITDIDF on $G$. In this paper, we establish various bounds on $\gamma_{tdI}^{oi}(G)$, and we determine this parameter for some special classes of graphs.

Abstract:
This paper presents an insertion procedure (IP) that can be used to improve the performance of multiobjective scheduling problems (MOSPs) algorithms. The proposed procedure uses variable neighborhood search (VNS) combined with an insertion method, which can be adapted to any MOSP, whether heuristic or metaheuristic. The aim is to solve 2-machine permutation flowshop scheduling problem (PFSP) and minimize two objective functions simultaneously: Maximum completion time (makespan) and total completion times (∑jCj) (TCT) in order to find the efficient (non dominated) solutions. The proposed IP is combined with two algorithms from the literature, the non dominated sorting genetic algorithm (NSGA-2) and the multiobjective partial enumeration algorithm (MOPE), the objective is to explore more non dominating solution by the use of insertion concept of jobs through all possible positions of the considered sequence. To evaluate the algorithms, a large set of test instances involving up to 80 jobs was used for our investigation. We found that using the IP procedure is very useful in improving the performance of multiobjective algorithms and that the proposal was very useful in producing good solutions compared to the original algorithms, as it used to improve the performance of both MOPE and MOGA.
