A graph rewriting programming language for graph drawing [PDF]

open access: yes, 1998
This paper describes Grrr, a prototype visual graph drawing tool. Previously there were no visual languages for programming graph drawing algorithms despite the inherently visual nature of the process.

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.

Total Semirelib Graph [PDF]

open access: yes, 2013
In this paper, the concept of Total semirelib graph of a planar graph is introduced. Authors present a characterization of those graphs whose total semirelib graphs are planar, outer planar, Eulerian, hamiltonian with crossing number ...

Pragmatic Graph Rewriting Modifications [PDF]

open access: yes, 1999
We present new pragmatic constructs for easing programming in visual graph rewriting programming languages. The first is a modification to the rewriting process for nodes the host graph, where nodes specified as 'Once Only' in the LHS of a rewrite match ...

The set chromatic numbers of the middle graph of graphs

open access: yesJournal of Physics: Conference Series, 2021
AbstractFor a simple connected graphG, letc:V(G) → ℕ be a vertex coloring ofG,where adjacent vertices may be colored the same. The neighborhood color set of a vertexv, denoted byNC(v), is the set of colors of the neighbors ofv. The coloringcis called aset coloringprovided thatNC(u) ≠NC(v) for every pair of adjacent verticesuandvofG.

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 ...

Exploring Ways to Improve Elementary School Statistics Education Through Analysis of Middle School Social Studies Textbooks: Focusing on Statistical Graph Teaching

open access: yesJournal of Educational Research in Mathematics, 2020
In this study, in order to explore ways that statistical graphs teaching in elementary mathematics education can be improved, first, the types of statistical graphs that appear in middle school social textbooks were examined, and second, the ...
