Rainbow Coloring In Graph Theory

Rainbow - Wikiwand

Rainbow coloring of a wheel graph, with three colors. Every two non-adjacent vertices can be connected by a rainbow path, either directly through the center vertex (bottom left) or by detouring around one triangle to avoid a repeated edge color (bottom right). In graph theory, a path in an edge.

The rainbow vertex connection number of a graph G is the smallest number of colors needed in one such coloring and is denoted rvc (G). More recently, Li et al. [12] defined a stronger variant of this problem by requiring that the rainbow paths connecting the pairs of vertices are also shortest paths between those pairs.

Computing the rainbow connection number of a graph is NP- hard and it finds its applications to the secure transfer of classified information between agencies and scheduling. In this paper the rainbow coloring of double triangular snake DTn was defined and the rainbow connection numbers rc(G) and rvc(G) have been computed.

1 Introduction We will almost entirely focus on coloring edges so "coloring" will mean edge coloring. In most cases, k will be used to denote the number of colors used on the edges. Also define the color degree dc(v) to be the number of colors on edges incident to v. A colored graph is called rainbow if each edge receives a distinct color.

First get a rainbow coloring of the connected dominating set. Then color the remaining edges in such a way that for each vertex x outside there are two disjoint rainbow colored paths (rainbow colored using different set of colors).

The rainbow vertex connection number of a graph G is the smallest number of colors needed in one such coloring and is denoted rvc (G). More recently, Li et al. [12] defined a stronger variant of this problem by requiring that the rainbow paths connecting the pairs of vertices are also shortest paths between those pairs.

In this paper, we introduce three new graph classes, namely tunjung graphs, sandat graphs, and jempiring graphs. We determine the rainbow connection number of the graphs.

This then results in a vertex coloring of the graph, often called a rainbow coloring since all vertex colors are distinct. Here, we consider edge colorings of graphs with positive integers such that each vertex color is the average of the colors of its incident edges and all vertex colors are distinct.

3) Online Rainbow Coloring: In online rainbow coloring, the inputs are a non-trivial un-directed connected simple graph G and a set of colors c. The output is a rainbow colored graph, where there must be atleast one rainbow path between every distinct pair of vertices. Our goal is to use minimum colors while making G rainbow colored. We have constraints such as the edges of G are unknown at.

Abstract - Rainbow vertex coloring introduced a decade ago followed by Rainbow dominator Coloring in recent years has been at tracting the researchers in graph theory. We undertake a study on rainbow vertex coloring and in particular rainbow dominator coloring for specific connected graphs namely Bull graph, Star graph, Complete graph, Helm graph and sunlet graph, Jelly fish, Jewel graph.
