On irregular total labellings

TL;DR: Two new graph characteristics, the total vertex irregularity strength and the total edge irregularitystrength, are introduced andEstimations on these parameters are obtained.
Journal ArticleDOI

Cayley graphs as classifiers for data mining: The influence of asymmetries

TL;DR: This paper proposes a new method of using Cayley graphs for classification of data using the endomorphism monoids of graphs, a convenient tools expressing asymmetries of the graphs.
Journal ArticleDOI

The train marshalling problem

TL;DR: The aim of this paper is to show that the decision problem: “Given numbers n,k and a partition S of {1,2,…,n}, is K(S)⩽k?” is NP-complete and to give a general upper bound for K( S) in terms of n.

On super (a,d)-edge-antimagic total labeling of disconnected graphs

TL;DR: In this article, the super (a,d)-edge-antimagic total properties of disconnected graphs mC"n and mP"n were studied, where the smallest possible labels appeared on the vertices.
