On the existence of a Hamiltonian path in a graph

Information and Control, 1968
A transition probability matrix is associated with an graph (X, T), and the classification of states in the homogenons Markov chain defined by this transition probability matrix is applied to a graph theory. Several sets of necessary and sufficient conditions for a graph to have a Hamiltonian circuit are obtained by means of the classification of these

Hardware‐Native Gaussian Sampling With Probabilistic Ising Machines for Modern Communication Paradigms

Advanced Science, EarlyView.
Probabilistic Ising machines are introduced as hardware‐native Gaussian samplers for edge communication workloads. Tunable variance and sampling density enable accurate distributions for Falcon‐class post‐quantum signatures and diffusion‐based semantic communication.

Spectrum and wave functions of excited states in lattice gauge theory [PDF]

, 2008
We suggest a new method to compute the spectrum and wave functions of excited states. We construct a stochastic basis of Bargmann link states, drawn from a physical probability density distribution and compute transition amplitudes between stochastic ...

Proving the existence of Euclidean knight's tours on n×n×...×n chessboards for n<4 [PDF]

Notes on Number Theory and Discrete Mathematics
The Knight's Tour problem consists of finding a Hamiltonian path for the knight on a given set of points so that the knight can visit exactly once every vertex of the mentioned set. In the present, we provide a 5-dimensional alternative to the well-known

Sliding Ferroelectric Metals: An Emerging Frontier

Advanced Science, EarlyView.
This Perspective highlights recent advances in sliding ferroelectric metals, focusing on the coexistence of switchable polarization and metallicity. Representative nonmagnetic and magnetic systems are discussed, together with Berry‐curvature memory, superconducting switching, triply‐coupled switching, magnetoelectric coupling, and electrically ...

Determination of the Shortest Hamiltonian Paths in an Arbitrary Graph of Distributed Databases

Российский технологический журнал, 2019
A method has been developed for finding the shortest Hamiltonian path in an arbitrary graph based on the rank approach, which provides high efficiency and a significant reduction in the error in solving the problem of organizing the process of managing ...

Hamiltonian Intervals in the Lattice of Binary Paths

The Electronic Journal of Combinatorics
Let $\mathcal{P}_n$ be the set of all binary paths (i.e., lattice paths with upsteps $u = (1,1)$ and downsteps $d = (1,-1)$) of length $n$ endowed with the pointwise partial ordering (i.e., $P \le Q$ iff the lattice path $P$ lies weakly below $Q$) and let $G_n$ be its Hasse graph.

Magnetoelectric Multiferroics for the Next‐Generation Ultralow‐Power Electronics

Advanced Science, EarlyView.
Magnetoelectric coupling provides a unifying route from electric‐field control of magnetic order to non‐volatile MeRAM, MESO logic, and emerging antiferromagnetic and magnonic devices. By connecting switching physics with device benchmarks, material platforms, and integration strategies, distinctive technological opportunities are identified alongside ...

µSlicer for Programmable Multimaterial 3D Printing

Advanced Science, EarlyView.
ABSTRACT Nature rarely builds with uniform materials; instead, it achieves exceptional performance by arranging composition and structure across multiple length scales. Mimicking such architectures has become increasingly feasible with additive manufacturing, and especially with multimaterial 3D printing, where complex structures with spatially varying
