On the graph of large distances [PDF]

open access: yesDiscrete & Computational Geometry, 1989
Let \(S\) be a set of \(n\) points in the plane and let \(d_1>d_2>..\). be the different distances determined by the set \(S\). The graph \(G(S,k)\) is considered whose vertex set is S and in which two vertices are adjacent if and only if their distance is at least \(k\). The chromatic number \(\chi(G(S,k))\) of \(G(S,k)\) is studied. It is proved that

Revisiting Volgenant-Jonker for Approximating Graph Edit Distance [PDF]

open access: yes, 2015
Although it is agreed that the Volgenant-Jonker (VJ) algorithm provides a fast way to approximate graph edit distance (GED), until now nobody has reported how the VJ algorithm can be tuned for this task.

The distance seidel spectrum of some graph operations [PDF]

open access: yesJournal of Hyperstructures
The distance matrix, distance eigenvalue, and distance energy of a connected graph have been studied in detail in literature where as the study on distance seidel matrix associated with a connected graph is in progress. The eigenvalues ∂1S≥∂2S≥ ...

Graph edit distance or graph edit pseudo-distance? [PDF]

open access: yes, 2016
Graph Edit Distance has been intensively used since its appearance in 1983. This distance is very appropriate if we want to compare a pair of attributed graphs from any domain and obtain not only a distance, but also the best correspondence between nodes

The distance spectrum of corona and cluster of two graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2015
Let G be a connected graph with a distance matrix D. The D-eigenvalues {μ1,μ2,…,…,μp} of G are the eigenvalues of D and form the distance spectrum or D-spectrum of G.
