Coloring Random Graphs [PDF]

open access: greenPhysical Review Letters, 2002
We study the graph coloring problem over random graphs of finite average connectivity $c$. Given a number $q$ of available colors, we find that graphs with low connectivity admit almost always a proper coloring whereas graphs with high connectivity are uncolorable.

Oriented Coloring on Recursively Defined Digraphs

open access: yesAlgorithms, 2019
Coloring is one of the most famous problems in graph theory. The coloring problem on undirected graphs has been well studied, whereas there are very few results for coloring problems on directed graphs. An oriented k-coloring of an oriented graph G =

Iterated colorings of graphs

open access: bronzeDiscrete Mathematics, 2003
Let \(P\) be a property of a set of vertices of a graph (e.g., being a maximal independent set in the graph). An iterated \(P\)-coloring of a graph is one that can be obtained through the following greedy algorithm (called iterated coloring algorithm by the authors): Repeatedly choose a set of vertices with property \(P\), color it with an unused color

on Graceful Chromatic Number of Vertex amalgamation of Tree Graph Family

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2022
Proper vertex coloring c of a graph G is a graceful coloring if c is a graceful k-coloring for k∈{1,2,3,…}. Definition graceful k-coloring of a graph G=(V,E) is a proper vertex coloring c:V(G)→{1,2,…,k);k≥2, which induces a proper edge coloring c':E(G ...

ON RAINBOW ANTIMAGIC COLORING OF SNAIL GRAPH(S_n ), COCONUT ROOT GRAPH (Cr_(n,m) ), FAN STALK GRAPH (Kt_n ) AND THE LOTUS GRAPH(Lo_n )

open access: yesBarekeng, 2023
Rainbow antimagic coloring is a combination of antimagic labeling and rainbow coloring. Antimagic labeling is labeling of each vertex of the graph  with a different label, so that each the sum of the vertices in the graph has a different weight. Rainbow

Coloring Drawings of Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2022
We consider cell colorings of drawings of graphs in the plane. Given a multi-graph $G$ together with a drawing $\Gamma(G)$ in the plane with only finitely many crossings, we define a cell $k$-coloring of $\Gamma(G)$ to be a coloring of the maximal connected regions of the drawing, the cells, with $k$ colors such that adjacent cells have different ...
