On distance dominator packing coloring in graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Let G be a graph and let S = (s1,s2,..., sk) be a non-decreasing sequence of positive integers. An S-packing coloring of G is a mapping c : V(G) ? {1, 2,..., k} with the following property: if c(u) = c(v) = i, then d(u,v) > si for any i ? {1, 2,...,k}.

Notes on complexity of packing coloring [PDF]

open access: yesInformation Processing Letters, 2017
A packing k-coloring for some integer k of a graph G = ( V , E ) is a mapping φ : V → { 1 , … , k } such that any two vertices u , v of color φ ( u ) = φ ( v ) are in distance at least φ ( u ) + 1 .

Algebraic and Combinatorial Algorithms for S-Packing Coloring

open access: yesACM Communications in Computer Algebra
S-packing coloring is a generalization of proper coloring of graphs, introduced more than a decade ago. In this paper, we present algebraic and combinatorial algorithms for the problem of S-packing coloring of finite undirected and unweighted graphs.

Packing list‐colorings

open access: yesRandom Structures & Algorithms, 2023
AbstractList coloring is an influential and classic topic in graph theory. We initiate the study of a natural strengthening of this problem, where instead of one list‐coloring, we seek many in parallel. Our explorations have uncovered a potentially rich seam of interesting problems spanning chromatic graph theory. Given a ‐list‐assignment of a graph ,

Packing coloring of Sierpiński-type graphs [PDF]

open access: yesAequationes mathematicae, 2017
The packing chromatic number $χ_ρ(G)$ of a graph $G$ is the smallest integer $k$ such that the vertex set of $G$ can be partitioned into sets $V_i$, $i\in \{1,\ldots,k\}$, where each $V_i$ is an $i$-packing. In this paper, we consider the packing chromatic number of several families of Sierpiński-type graphs.

Online Vector Bin Packing and Hypergraph Coloring Illuminated: Simpler Proofs and New Connections [PDF]

open access: yesLatin-American Algorithms, Graphs and Optimization Symposium, 2023
This paper studies the online vector bin packing (OVBP) problem and the related problem of online hypergraph coloring (OHC). Firstly, we use a double counting argument to prove an upper bound of the competitive ratio of $FirstFit$ for OVBP.

On Colorful Bin Packing Games [PDF]

open access: yes, 2018
We consider colorful bin packing games in which selfish players control a set of items which are to be packed into a minimum number of unit capacity bins. Each item has one of $m\geq 2$ colors and cannot be packed next to an item of the same color. All bins have the same unitary cost which is shared among the items it contains, so that players are ...
