Characterization of Graphs Without Even F $F$‐Orientations

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A graph G $G$ is 1‐extendable if every edge belongs to at least one 1‐factor of G $G$. Let G $G$ be a graph with a 1‐factor F $F$. Then an even (odd) F $F$ ‐orientation of G $G$ is an orientation in which each F $F$‐alternating cycle has exactly an even (odd) number of edges directed in the same fixed direction around the cycle.

Revisiting the cardinality operator and introducing the cardinality-path constraint family

open access: yes, 2001
This paper presents generic propagation algorithms for the cardinality-path constraint family. This is a restricted form of the cardinality operator that allows stating constraints on sliding sequences of consecutive variables.

The 1 3 $\frac{1}{3}$‐Conjectures for Domination in Cubic Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A set S $S$ of vertices in a graph G $G$ is a dominating set of G $G$ if every vertex not in S $S$ is adjacent to a vertex in S $S$. The domination number of G $G$, denoted by γ ( G ) $\gamma (G)$, is the minimum cardinality among all dominating sets in G $G$. In a breakthrough paper in 2008, Löwenstein and Rautenbach proved that if G $G$ is a

A Structural Description of Zykov and Blanche Descartes Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Around 1950, Zykov and Blanche Descartes proposed the two first explicit constructions of triangle‐free graphs with arbitrarily large chromatic number. We define a Zykov (resp. Blanche Descartes) graph as any induced subgraph of a graph created using Zykov's construction (resp. Blanche Descartes's).

A framework for estimating xml query cardinality

open access: yes, 2003
. In the context of XML data management systems, the estimation of query cardinality is becoming more and more important: the information provided by a query result estimator can be used as input to the query optimizer, as an early feedback to user ...

Limbic Structural Alterations and Structural Covariance Across Prodromal Phenotypes and Early Parkinson's Disease

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Non‐motor symptoms may precede motor diagnosis in Parkinson's disease (PD), but whether distinct prodromal phenotypes exhibit differential limbic structural alterations remains unclear. Purpose To investigate limbic structural alterations across prodromal PD phenotypes defined by rapid eye movement sleep behavior disorder (RBD) and ...

Evolutionary dynamics on a regular networked structured and unstructured multi‐population

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.
