A logical model of HCP

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
For an arbitrary undirected graph G, we are designing a logical model for the Hamiltonian Cycle Problem (HCP), using tools of Boolean algebra only. The obtained model is a logic formulation of the conditions for the existence of the Hamiltonian cycle ...

On Hamiltonian Cycles in Claw-Free Cubic Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We show that every claw-free cubic graph of order n at least 8 has at most 2⌊n4⌋{2^{\left\lfloor {{n \over 4}} \right\rfloor }} Hamiltonian cycles, and we also characterize all extremal graphs.

A Note on Cycles in Locally Hamiltonian and Locally Hamilton-Connected Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let 𝒫 be a property of a graph. A graph G is said to be locally 𝒫, if the subgraph induced by the open neighbourhood of every vertex in G has property 𝒫. Ryjáček conjectures that every connected, locally connected graph is weakly pancyclic.

Hamiltonian cycles and travelling salesfolk

open access: yesInternational Journal of Science and Research (IJSR), 2023
A method is given in this paper that makes it easier to solve both the Hamiltonian cycle problem and the travelling salesman problem in any number of space dimensions and in both their directed and undirected varieties.

Hamiltonian cycle clustering with asymmetric correlation

open access: yesVisual Informatics
Analysts who explore high-dimensional data usually want three answers at once: Which samples belong together, how close the resulting groups are, and who influences whom accordingly.

On the Hamiltonian Number of a Plane Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2019
The Hamiltonian number of a connected graph is the minimum of the lengths of the closed spanning walks in the graph. In 1968, Grinberg published a necessary condition for the existence of a Hamiltonian cycle in a plane graph, formulated in terms of the ...
