Graph Theory II 1 Coloring GraphsDevadas, SriniLehman, EricNotes, Lecture
Finding the chromatic number of a graph is difficult and belongs to theNP-completeclass. Hence, it’s unlikely that there’s an efficient algorithm to solve it for all graphs. However, for certain special classes of graphs, efficient algorithms exist. 3. Example Let’s take a graph in orde...

Generalized Fractional Total Colorings of Graphs We show in this paper that χ″,P,Q of a graph G with o(V (G)) vertex orbits and o(E(G)) edge orbits can be found as a solution of a ... G Karafová,R Soták - 《Discussiones Mathematicae Graph Theory》 被引量: 3发表: 2015年...
The bound above implies that BBC(G,T)≤Δ+2 if the backbone graph is a forest T and we improve this bound by showing BBC(G,M)≤Δ+1 in the case that the backbone graph is a matching M. We also show that there are non-trivial classes of graphs where these bounds are sharp. We...
NS Narayanaswamy,RS Babu - 《Order-a Journal on the Theory of Ordered Sets & Its Applications》 被引量: 87发表: 2008年 On b-colorings in regular graphs Summary: A $b$-coloring is a coloring of the vertices of a graph such that each color class contains a vertex that has a neighbor...
Considerable literature in the field of graph theory has dealt with the coloring of graphs. The majority of this effort has been devoted to the theory of graph coloring, and relatively little study has been directed toward the design of efficient graph coloring procedures. Because numerous proofs ...
