Hamilton cycles and algorithms [PDF]

open access: yes, 2022
We present three results in graph theory, united by the themes of Hamilton cycles and algorithms. A Hamilton cycle in a graph is a cycle that contains every vertex of the graph.

Hamilton Cycles in Double Generalized Petersen Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
Coxeter referred to generalizing the Petersen graph. Zhou and Feng modified the graphs and introduced the double generalized Petersen graphs (DGPGs). Kutnar and Petecki proved that DGPGs are Hamiltonian in special cases and conjectured that all DGPGs are

Connectivity and Hamiltonicity of Canonical Colouring Graphs of Bipartite and Complete Multipartite Graphs

open access: yesAlgorithms, 2018
A k-colouring of a graph G with colours 1 , 2 , … , k is canonical with respect to an ordering π = v 1 , v 2 , … , v n of the vertices of G if adjacent vertices are assigned different colours and, for 1 ≤ c ≤ k

A Note Concerning Hamilton Cycles in Some Classes of Grid Graphs

open access: yesJournal of Mathematical and Fundamental Sciences, 2013
A graph G is called hamiltonian if it contains a Hamilton cycle, i.e. a cycle containing all vertices. Deciding whether a given graph has a Hamilton cycle is an NP-complete problem. But, it is a polynomial problem within some special graph classes.

Two Sufficient Conditions for Hamilton and Dominating Cycles

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
We prove that if is a 2-connect graph of size (the number of edges) and minimum degree with , where when and when , then each longest cycle in is a dominating cycle.

Graph Invariants and Large Cycles: A Survey

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
Graph invariants provide a powerful analytical tool for investigation of abstract substructures of graphs. This paper is devoted to large cycle substructures, namely, Hamilton, longest and dominating cycles and some generalized cycles including Hamilton ...
