Testo completoThis thesis is decomposed in three disjoint parts. The first two parts delve into dynamically growing networks. In the first part, we infer information about the past from a snapshot of the graph. We start by the problem of root finding, where the goal is to find confidence set for the root. We propose a method for uniform L-dags and analyse its performance. It is, to the best of our knowledge, the first method achieving network archaeology in general graphs. Then, we naturally extend the question of root finding to the one of seriation. Given a snapshot of a graph, is it possible to retrieve its whole ordering? We present a method and statistical guarantee of its quality in the case of uniform random recursive trees and linear preferential attachment tree. To conclude the network archaeology section, we study the root bit finding problem, where one does not try to infer the position of the root but its state. In such problems, the root is assigned a bit and is then propagated through a noisy channel during network growth. In the L-dag, we study majority voting to infer the bit of the root and we identify three different regimes depending on the noise level. In the second part of this thesis, we study the so called friendship tree, which is a random recursive tree model with complete redirection. This model display emerging properties, but unlike in the preferential attachment model they stem from a local attachment rule. We prove conjectures about degree distribution, diameter and local structure. Finally, we delve into the world of theoretical machine learning and data analysis. We study a random approximation of the Tukey depth. The Tukey depth is a powerful tool for data visualization and can be thought of as an extension of quantiles in higher dimension (they coincide in dimension 1). Its exact computation is NP-hard, and we study the performances of a classical random approximation in the case of data sets sampled from log-concave distribution

Testo completologiciel à partir d'une description graphique des comportements du
système à tester (graphe de contrôle, statecharts). Son originalité
repose sur la combinaison de résultats et d'outils de combinatoire
(génération aléatoire de structures combinatoires) et d'un solveur de
contraintes, pour obtenir une méthode de test complètement automatisée.
Contrairement aux approches classiques qui tirent des entrées, la
génération aléatoire uniforme est utilisée pour tirer des chemins parmi
un ensemble de chemins d'exécution ou de traces du système à tester.
Puis, une étape de résolution de contraintes est utilisée pour
déterminer les entrées qui permettront d'exécuter ces chemins.
De plus, nous montrons comment les techniques de programmation
linéaire peuvent améliorer la qualité d'un ensemble de tests.
Une première application a été effectuée pour le test statistique
structurel défini par Thévenod-Fosse et Waeselynck (LAAS) et un
prototype a été développé.
Des expériences (plus de 10000 réalisées sur quatre fonctions issues
d'un logiciel industriel) ont été effectuées pour évaluer notre approche
et sa stabilité.
Ces expériences montrent que notre approche est comparable à celle
du LAAS, est stable et a l'avantage d'être complètement automatisée.
Ces premières expériences nous permettent également d'envisager un
passage à l'échelle de notre approche. Plus généralement, ces travaux
pourraient servir de base pour une nouvelle classe d'outils dans le
domaine du test de logiciel, combinant génération aléatoire de
structures combinatoires, techniques de programmation linéaire et
résolution de contraintes.

Testo completoThis thesis focuses on the development of combinatorial methods for testing and formal verification. Particularly on probabilistic approaches because exhaustive verification is often not tractable for complex systems. For model-based testing, I guide the random exploration of the model to ensure a satisfaction with desired probability of the expected coverage criterion, regardless of the underlying topology of the explored model. Regarding model-checking, I show how to generate a random number of finite paths to check if a property is satisfied with a certain probability. In the first part, I compare different algorithms for generating uniformly at random paths in an automaton. Then I propose a new algorithm that offers a good compromise with a sub-linear space complexity in the path length and a almost-linear time complexity. This algorithm allows the exploration of large models (tens of millions of states) by generating long paths (hundreds of thousands of transitions). In a second part, I present a way to combine partial order reduction and on-the-fly generation techniques to explore concurrent systems without constructing the global model, but relying on models of the components only. Finally, I show how to bias the previous algorithms to satisfy other coverage criteria. When a criterion is not based on paths, but on a set of states or transitions, we use a mixed solution to ensure both various ways of exploring those states or transitions and the criterion satisfaction with a desired probability

Testo completoThis thesis is at the interface between combinatorics and probability,and contributes to the study of a few models stemming from statisticalmechanics: polymers, self-interacting random walks and random walks inrandom environment, random maps.bigskipThe first model that we investigate is a one-parameter family ofprobability measures on self-avoiding paths of infinite length on aregular lattice, constructed from biased random walks on the tree offinite self-avoiding paths. These measures, initially introduced byBeretti and Sokal, exist for every bias larger than the inverseconnectivity constant, and their limit at the critical bias would beaamong the natural definitions of the uniform self-avoiding walk ofinfinite length. The aim of our work, in collaboration with VincentBeffara, is to understand the link between this limit, if it indeedexists, and other random infinite paths such as Kesten's measure(which is the weak limit of uniformly random finite self-avoidingwalks in the half-plane) and critical Bernoulli percolationinterfaces; the model can be seen as an interpolation between thesetwo.In a second part, we consider random walks with random conductances ona tree, in the case when the law of the conductances has heavy tail.Our aim, in collabration with Andrea Collevecchio and Daniel Kious, isto show a phase transition in the tail parameter; we express thecritical point as an explicit function of the underlying tree.In parallel, we study excited random walks on trees and their phasetransitions: we extend a conjecture of Volkov's and generalize resultsby Basdevant and Singh.Finally, a third part in collaboration with Vincent Beffara andBenjamin Lévêque contributes to the study of random maps of highergenus: we show the existence of subsequential scaling limits foruniformly random simple triangulations of the torus, extending to thatsetup fromer results by Adario-Berri and Albenque (on simpletriangulations of the sphere) and by Bettinelli (on quadrangulationsof the torus). The question of uniqueness and universality of thelimit remain open, but we obtain partial results in that direction

Testo completoA relatively new combinatorial structure, called staircase tableaux, was introduced in recent work of S. Corteel and L. Williams. Staircase tableaux are a generalisation of permutation tableaux and alternative tableaux. Their study gave a combinatorial formula for the moments of Askey-Wilson polynomials. Staircase tableaux are also related to the asymmetric exclusion process on a one-dimensional lattice with open boundaries (ASEP), an important and heavily studied particle model in statistical mechanics. The study of the generating function of the staircase tableau has given a combinatorial formula for the steady state probability of the ASEP. We use differents approaches to study the staircase tableaux : with a probabilistic approach, we prove the asymptotic normality of some parameters of the staircase tableaux ; with bijective combinatorics, we get the properties of some subsets of staircase tableaux, using for example tree-like tableaux or permutations. Finally, a Markov chain on a subset of staircase tableaux confirms intuitively the formula for the steady state probability without using the matrix ansatz
