The b-chromatic number of a graph G is the largest integer k, such that G admits a proper k-
coloring in which every color class contains at least one vertex that has a neighbor in each …

Given a graph G=(V, E), the b-coloring problem consists in attributing a color to every vertex
in V such that adjacent vertices receive different colors, every color has a b-vertex, and the …

coloring in which every color class contains at least one vertex that has a neighbor in each …

A b-coloring of a graph G by k colors is a proper k-coloring of G such that in each color class
there exists a vertex having neighbors in all the other k− 1 color classes. The b-chromatic …

A b-coloring of the vertices of a graph is a proper coloring where each color class contains a
vertex which is adjacent to at least one vertex in each other color class. The b-chromatic …

B-coloring is a theoretical optimization problem on a graph that, on top of being used to
model some real-world applications, is exploited by some bounding techniques embedded …

A common way to tackle the computational intractability of combinatorial problems on
graphs is to impose restrictions on the input graphs that can be exploited in the design of …

The b-chromatic number of a graph G, denoted by φ (G), is the largest integer k for which G
admits a proper coloring by k colors, such that each color class has a vertex that is adjacent …

A b-coloring is a proper vertex coloring of a graph such that each color class contains a
vertex that has a neighbor in all other color classes and the b-chromatic number is the …
