Calculating the number of Hamilton cycles in layered polyhedral graphs

open access: yesComput. Math. Methods, 2020
We describe a method for computing the number of Hamilton cycles in cubic polyhedral graphs. The Hamilton cycle counts are expressed in terms of a finite-state machine, and can be written as a matrix expression.

Loose Hamilton Cycles in Regular Hypergraphs [PDF]

open access: yesCombinatorics, Probability and Computing, 2014
We establish a relation between two uniform models of randomk-graphs (for constantk⩾ 3) onnlabelled vertices: ℍ(k)(n,m), the randomk-graph with exactlymedges, and ℍ(k)(n,d), the randomd-regulark-graph. By extending the switching technique of McKay and Wormald tok-graphs, we show that, for some range ofd = d(n)and a constantc> 0, ifm~cnd, then one ...

Method to generate the pseudo random sequence based on the statistical properties

open access: yes网络与信息安全学报, 2017
There are some problems existing in pseudo-random sequence generating methods, such as the weaker proportionality, bad run length characteristic, etc. Hence, based on the SimiHam algorithm in Knight's tour problem, a pseudo-random sequences generating ...

A High-Resolution Lead-Lag Analysis of US GDP, Employment, and Unemployment 1977–2021: Okun’s Law and the Puzzle of Jobless Recovery

open access: yesEconomies, 2022
Okun’s law is formulated as the ratio between GDP and unemployment (UE): β = f(GDP/UE). It is used to investigate the relations between output and labor input across regions or across business cycles. Based on results by James D. Hamilton we replaced the

Pattern Colored Hamilton Cycles in Random Graphs [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2017
We consider the existence of patterned Hamilton cycles in randomly colored random graphs. Given a string $\Pi$ over a set of colors $\{1,2,\ldots,r\}$, we say that a Hamilton cycle is $\Pi$-colored if the pattern repeats at intervals of length $|\Pi|$ as

Nestmate Copulation in the Neotropical Eusocial Wasp Polistes Instabilis de Saussure (Hymenoptera: Vespidae)

open access: yesPsyche: A Journal of Entomology, 1994
Copulation between individually marked nestmates of the Neotropical eusocial wasp Polistes instabilis is reported. Polistes copulations are rarely observed in the field; this observation is the first documented case of nestmate copulation in the genus ...

Grafos hamiltonianos en el diseño de viajes

open access: yesModelling in Science Education and Learning, 2013
The existence and, if applicable, the location of paths with given properties is a topic in graph theory. One of these problems is to find routes through all points, only once, starting and ending at the same node.

Comparison of HP Filter and the Hamilton’s Regression

open access: yesMathematics, 2022
In this paper we examine if the use of Hamilton’s regression filter significantly modifies the cyclical components concerning unemployment in Greece compared with those using the Hodrick–Prescott double filter (HP).

On Rainbow Hamilton Cycles in Random Hypergraphs [PDF]

open access: yesElectronic Journal of Combinatorics, 2017
Let $H_{n,p,r}^{(k)}$ denote a randomly colored random hypergraph, constructed on the vertex set $[n]$ by taking each $k$-tuple independently with probability $p$, and then independently coloring it with a random color from the set $[r]$. Let $H$ be a $k$
