On the Total Graph of Mycielski Graphs, Central Graphs and Their Covering Numbers

open access: yesDiscussiones Mathematicae Graph Theory, 2013
The technique of counting cliques in networks is a natural problem. In this paper, we develop certain results on counting of triangles for the total graph of the Mycielski graph or central graph of star as well as completegraph families.

Compiler Optimization: A Case for the Transformation Tool Contest [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
An optimizing compiler consists of a front end parsing a textual programming language into an intermediate representation (IR), a middle end performing optimizations on the IR, and a back end lowering the IR to a target representation (TR) built of ...

Hamiltonicity of complements of middle graphs

open access: yesDiscrete Mathematics, 2007
Let \(G(V,E)\) be an undirected finite simple graph. The middle graph \(M(G)\) of \(G\) has the vertex set \(V(G)\cup E(G)\) and two vertices \(x,y\) of \(M(G)\) are adjacent in \(M(G)\) if at least one of them corresponds to an edge \(e\) of \(G\) and the other one is either one of the endvertices of \(e\) in \(G\), or corresponds to an edge \(f\) of \

On the Boolean function graph of a graph and on its complement [PDF]

open access: yes, 2005
summary:For any graph $G$, let $V(G)$ and $E(G)$ denote the vertex set and the edge set of $G$ respectively. The Boolean function graph $B(G,L(G),\mathop {\mathrm NINC})$ of $G$ is a graph with vertex set $V(G)\cup E(G)$ and two vertices in $B(G,L(G ...
