New Sufficient Conditions for Hamiltonian Paths [PDF]

open access: yesThe Scientific World Journal, 2014
A Hamiltonian path in a graph is a path involving all the vertices of the graph. In this paper, we revisit the famous Hamiltonian path problem and present new sufficient conditions for the existence of a Hamiltonian path in a graph.

Covariant Hamiltonian field theory. Path integral quantization [PDF]

open access: yesInternational Journal of Theoretical Physics, 2004
The Hamiltonian counterpart of classical Lagrangian field theory is covariant Hamiltonian field theory where momenta correspond to derivatives of fields with respect to all world coordinates.

Absolute Differences Along Hamiltonian Paths

open access: diamondThe Electronic Journal of Combinatorics, 2015
We prove that if the vertices of a complete graph are labeled with the elements of an arithmetic progression, then for any given vertex there is a Hamiltonian path starting at this vertex such that the absolute values of the differences of consecutive vertices along the path are pairwise distinct.

DISTRIBUTED HAMILTONIAN PATH SEARCH ALGORITHM

open access: yesPerner’s Contacts, 2010
Many practical problems of transportation can be transformed to the problem of finding Hamiltonian path or circle. It was proven, that this problem is NP-complete and thus can be very time-consuming for practical problem size. In this paper we present a

Quantum Zeno approach for molecular energies with maximum commuting initial Hamiltonians

open access: yesPhysical Review Research, 2021
We propose to use a quantum adiabatic and simulated-annealing framework to compute the ground state of small molecules. The initial Hamiltonian of our algorithms is taken to be the maximum commuting Hamiltonian that consists of a maximal set of commuting

Hamiltonian Cycle Problem in Strong k-Quasi-Transitive Digraphs With Large Diameter

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Let k be an integer with k ≥ 2. A digraph is k-quasi-transitive, if for any path x0x1... xk of length k, x0 and xk are adjacent. Let D be a strong k-quasi-transitive digraph with even k ≥ 4 and diameter at least k +2.

Proper Hamiltonian Paths in Edge-Coloured Multigraphs [PDF]

open access: greenGraphs and Combinatorics, 2014
Given a $c$-edge-coloured multigraph, a proper Hamiltonian path is a path that contains all the vertices of the multigraph such that no two adjacent edges have the same colour. In this work we establish sufficient conditions for an edge-coloured multigraph to guarantee the existence of a proper Hamiltonian path, involving various parameters as the ...

Hamiltonian Extendable Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
A graph is called Hamiltonian extendable if there exists a Hamiltonian path between any two nonadjacent vertices. In this paper, we give an explicit formula of the minimum number of edges for Hamiltonian extendable graphs and we also characterize the ...
