Connected Domination Number and a New Invariant in Graphs with Independence Number Three [PDF]
Adding a connected dominating set of vertices to a graph $G$ increases its number of Hadwiger $h(G)$. Based on this obvious property in [2] we introduced a new invariant $\eta(G)$ for which $\eta(G)\leq h(G)$. We continue to study its property.

Eternal domination and clique covering
We study the relationship between the eternal domination number of a graph and its clique cove-ring number using both large-scale computation and analytic methods. In doing so, we answer two open questions of Klostermeyer and Mynhardt.

On a class of polynomials associated with the Cliques in a graph and its applications
The clique polynomial of a graph is defined. An explicit formula is then derived for the clique polynomial of the complete graph. A fundamental theorem and a reduction process is then given for clique polynomials.

Perfect folding of graphs [PDF]
In this paper we introduced the definition of perfect foldingof graphs and we proved that cycle graphs of even number ofedges can be perfectly folded while that of odd number ofedges can be perfectly folded to C3 .

Clique-to-Clique Monophonic Distance in Graphs
It is shown that the clique-to-clique monophonic center a connected graph does not lie in a single block of G.

Structural Parameterizations of Clique Coloring [PDF]
A clique coloring of a graph is an assignment of colors to its vertices such that no maximal clique is monochromatic. We initiate the study of structural parameterizations of the Clique Coloring problem which asks whether a given graph has a clique ...

shah314/clique: Genetic Algorithm for the Maximum Clique Problem
<p>Implementation of a genetic algorithm for the maximum clique problem in C++. A clique of a graph is a set of vertices in which each pair in the set have an edge between them i.e. it is a complete subgraph.

On General Reduced Second Zagreb Index of Graphs
Graph-based molecular structure descriptors (often called “topological indices”) are useful for modeling the physical and chemical properties of molecules, designing pharmacologically active compounds, detecting environmentally hazardous substances, etc.
