Arbres couvrants presque disjoints

2015

International audience; Dans un réseau, la recherche de plusieurs arbres couvrants avec des propriétés intéressantes a amené à l'introduc-tion de plusieurs notions : les arbres couvrants arête-disjoints, les arbres indépendants enracinés en un sommet et les arbres complètement indépendants. Afin de généraliser ces notions, nous introduisons la notion d'arbres couvrants (i, j)-disjoints, où i et j sont respectivement le nombre maximum de noeuds internes et d'arêtes communs aux arbres couvrants. Nous montrons que déterminer s'il existe deux arbres couvrants (i, j)-disjoints dans un graphe G est un problème NP-complet pour i et j quelconques, et nous déterminons les valeurs minimales de i et j…

Condensed representation of multidimensional association rules

2019

La fouille de règles d'association est un problème qui a donné lieu à une littérature foisonnante, notamment dans les données binaires bidimen-sionnelles classiques. En particulier, la relation entre les ensembles fermés et les règles d'association est bien connue. Tel n'est pas le cas dans les données multidimensionnelles. Dans ce papier, nous montrons que la connaissance des n-ensembles fermés d'un tenseur booléen multidimensionnel est suffisante pour inférer la confiance de toutes les règles d'association multidimensionnelles.

Vertex Distinguishing Edge- and Total-Colorings of Cartesian and other Product Graphs

2012

International audience; This paper studies edge- and total-colorings of graphs in which (all or only adjacent) vertices are distinguished by their sets of colors. We provide bounds for the minimum number of colors needed for such colorings for the Cartesian product of graphs along with exact results for generalized hypercubes. We also present general bounds for the direct, strong and lexicographic products.

Presentations of constrained systems with unconstrained positions

2005

International audience; We give a polynomial-time construction of the set of sequences that satisfy a finite-memory constraint defined by a finite list of forbidden blocks, with a specified set of bit positions unconstrained. Such a construction can be used to build modulation/error-correction codes (ECC codes) like the ones defined by the Immink-Wijngaarden scheme in which certain bit positions are reserved for ECC parity. We give a lineartime construction of a finite-state presentation of a constrained system defined by a periodic list of forbidden blocks. These systems, called periodic-finite-type systems, were introduced by Moision and Siegel. Finally, we present a linear-time algorithm for con…

Equivalence classes of Dyck paths modulo some statistics

2015

International audience; We investigate new equivalence relations on the set $\mathcal{D}_n$ of Dyck paths relatively to the three statistics of double rises, peaks and valleys. Two Dyck paths ar $r$-equivalent (resp. $p$-equivalent and $v$-equivalent) whenever the positions of their double rises (res. peaks and valleys) are the same. Then, we provide generating functions for the numbers of $r$-, $p$- and $v$-equivalence classes of $\mathcal{D}_n$.
