چکیده
A Meyniel graph is a graph in which every odd cycle of length at least five has two chords. We present a linear-time algorithm that colors optimally the vertices of a Meyniel graph and finds a clique of maximum size.

Erratum : MCColor is not optimal on Meyniel graphs
A Meyniel graph is a graph in which every odd cycle of length at least five has two chords. In [2] we claimed that our algorithm MCColor produces an optimal coloring for every Meyniel graph. But later we found a mistake in the proof and a couterexample to the optimality, which we present here. MCColor can still be used to find a stable set that intersects all maximal cliques of a Meyniel graph ...
متن کاملA linear algorithm for coloring vertices of a graph or finding a Meyniel obstruction
A Meyniel obstruction is an odd cycle with at most one chord and a graph is Meyniel if and only if it has no Meyniel obstruction. The authors have found in a previous work a linear-time algorithm for optimaly color the vertices of a Meyniel graph. Here we extend this algorithm to obtain a linear-time algorithm that, for any graph, colors optimally the vertices of the graph or finds a Meyniel ob...
متن کاملPrecoloring Extension of Co-Meyniel Graphs
The pre-coloring extension problem consists, given a graph G and a subset of nodes to which some colors are already assigned, in finding a coloring of G with the minimum number of colors which respects the pre-coloring assignment. This can be reduced to the usual coloring problem on a certain contracted graph. We prove that pre-coloring extension is polynomial for complements of Meyniel graphs....

متن کاملA practical algorithm for [r, s, t]-coloring of graph
Coloring graphs is one of important and frequently used topics in diverse sciences. In the majority of the articles, it is intended to find a proper bound for vertex coloring, edge coloring or total coloring in the graph. Although it is important to find a proper algorithm for graph coloring, it is hard and time-consuming too. In this paper, a new algorithm for vertex coloring, edge coloring an...
