Hamiltonian cycle problem and Markov chains

open access: yes, 2014
This book summarizes a line of research that maps certain classical problems of discrete mathematics and operations research - such as the Hamiltonian cycle and the Travelling Salesman problems - into convex domains where continuum analysis can be ...

A Conjecture on Rainbow Hamiltonian Cycle Decomposition [PDF]

open access: yes
Wu in 1999 conjectured that if $H$ is a subgraph of the complete graph $K_{2n+1}$ with $n$ edges, then there is a Hamiltonian cycle decomposition of $K_{2n+1}$ such that each edge of $H$ is in a separate Hamiltonian cycle.

Planar Hamiltonian Chordal Graphs are Cycle Extendible

open access: yes, 1997
A cycle C in a graph G is extendible if there exists a cycle C 0 in G such that V (C) ` V (C 0 ) and jV (C 0 )j = jV (C)j + 1. A graph G is cycle extendible if G contains at least one cycle and every nonhamiltonian cycle in G is extendible. A graph

The Square of a Hamiltonian Cycle

SIAM Journal on Discrete Mathematics, 1994
Let C be a cycle. The square of C is the graph obtained by joining every pair of vertices of distance 2 in C. Let G be a graph on n vertices with minimum degree $\delta ( G )$. This paper proves that, if $\delta ( G ) \geq \frac{5}{7}n$, then G contains the square of a Hamiltonian cycle.

Hamiltonian Cycles and Markov Chains

Mathematics of Operations Research, 1994
In this paper we derive new characterizations of the Hamiltonian cycles of a directed graph, and a new LP-relaxation of the Traveling Salesman Problem. Our results are obtained via an embedding of these combinatorial optimization problems in suitably perturbed controlled Markov chains.

A Remark on Hamiltonian Cycles

Mathematische Nachrichten, 1992
AbstractLet G be an undirected and simple graph on n vertices. Let ω, α and χ denote the number of components, the independence number and the connectivity number of G. G is called a 1‐tough graph if ω(G – S) ⩽ |S| for any subset S of V(G) such that ω(G − S) > 1.

On Hamiltonian cycles in the FCC grid

Computers & Graphics, 2020
Abstract The face centered cubic (FCC) grid is a space-filling grid, one of the alternatives to the traditional cubic one. We show that there are five Hamiltonian cycles (non-equivalent up to rotation and symmetry), connecting the faces of a voxel in the FCC grid.
