Rainbow vertex connection number and strong rainbow vertex connection number on slinky graph (SlnC4))

open access: yesDesimal, 2021
A graph is said rainbow connected if no path has more than one vertices of the same color inside. The minimum number of colors required to make a graph to be rainbow vertex-connected is called rainbow vertex connection-number and denoted by rvc(G ...

Rainbow connections of bioriented graphs [PDF]

open access: yesHeliyon
For a directed graph D, it's deemed rainbow connected if each arc is assigned a different color, so that all paths from the vertex u to the vertex v are rainbow connected.

Rainbow Vertex-Connection and Forbidden Subgraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A path in a vertex-colored graph is called vertex-rainbow if its internal vertices have pairwise distinct colors. A vertex-colored graph G is rainbow vertex-connected if for any two distinct vertices of G, there is a vertex-rainbow path connecting them ...

On the Rainbow Vertex-Connection

open access: yesDiscussiones Mathematicae Graph Theory, 2013
A vertex-colored graph is rainbow vertex-connected if any two vertices are connected by a path whose internal vertices have distinct colors. The rainbow vertex-connection of a connected graph G, denoted by rvc(G), is the smallest number of colors that ...

The complexity of determining the rainbow vertex-connection of a graph

open access: yesTheoretical Computer Science, 2011
A vertex-colored graph is {\it rainbow vertex-connected} if any two vertices are connected by a path whose internal vertices have distinct colors, which was introduced by Krivelevich and Yuster. The {\it rainbow vertex-connection} of a connected graph $G$, denoted by $rvc(G)$, is the smallest number of colors that are needed in order to make $G ...

The Rainbow (Vertex) Connection Number of Pencil Graphs

open access: yesProcedia Computer Science, 2015
AbstractAn edge colored graph G = (V(G), E(G)) is said rainbow connected, if any two vertices are connnected by a path whose edges have distinct colors. The rainbow connection number of G, denoted by rc(G), is the smallest positive integer of colors needed in order to make G rainbow connected. The vertex-colored graph G is said rainbow vertex-connected,
