Duhaze-Pradines, Loric. "Reachability problems for general rotor walks in graphs." Electronic Thesis or Diss., université Paris-Saclay, 2023. http://www.theses.fr/2023UPASG051.
Full textIn this thesis, we focus on the algorithmic properties of a cellular automaton known as rotor walks. This model has been introduced in two distinct ways. Firstly, as a fundamental operation within another cellular automaton known as Sandpiles, which models the collapse of a sand pile when it becomes too high. Secondly, due to its resemblance to well-studied stochastic models, such as random walks. Indeed, numerous structural properties of random walks (hitting times, cover times, etc.) are analogous to those of this completely deterministic automaton called the rotor walk. The main motivation for this thesis stems from this "derandomization" of a random process. More precisely, a rotor walk corresponds to the movement of a particle on a directed graph following the following rule: initially, an order (a numbering) is fixed on the outgoing arcs of each vertex of the graph. Once the starting position of the particle is defined, each time it is on a vertex, it leaves through the arc with the lowest value that it has not already used. Of course, if all arcs have been used, the process restarts with the lowest value arc. There is a multitude of accessibility problems on rotors, and we aim to compile a list of them in this thesis. We also provide complexity results for some of these problems. Subsequently, we turn our attention to a specific accessibility problem: ARRIVAL. Considering a graph with sinks such that there is a directed path between each vertex of the graph and at least one of these sinks, a rotor walk inevitably terminates. Unfortunately, the number of steps before this process concludes can be exponential. In 2017, Dorhau et al. introduced a problem called ARRIVAL, which seeks to determine if the particle successfully reaches a given sink. They demonstrated that it belongs to the complexity classes NP and co-NP. Being a strong candidate for polynomial algorithm resolution, we investigate this problem on a subclass of graphs where the step count of the process can be exponential: Tree-like multigraphs. These are multigraphs whose underlying undirected graph is a tree. In this context, we show that this problem can be solved in linear time, extending these results to decision versions of the ARRIVAL problem, known to be respectively NP-complete and PSPACE-complete

Full textO problema da determinação de percursos a efectuar por veículos afectos à remoção de resíduos sólidos urbanos pode ser visto como um problema de optimização de rotas, com procura nos arcos e restrições adicionais. Usualmente os algoritmos para determinar soluções admissíveis para este tipo de problemas não têm em conta o tipo de viragem que os veículos são obrigados a fazer. Dadas as características dos veículos envolvidos na recolha de resíduos, entende-se por má viragem uma inversão de marcha ou uma viragem à esquerda. Na prática é, em geral, exigida a minimização do número de más viragens, devendo mesmo algumas ser impossibilitadas, quer por se tornarem perigosas, quer por questões de regras de trânsito. Neste trabalho o problema da minimização do número de más viragens é definido e modelizado como um problema de redes. São desenvolvidos métodos para a determinação de soluções admissíveis. Os métodos implementados são testados num conjunto de problemas teste gerados aleatoriamente. Como se mostra, os resultados podem ser considerados bastante bons, dado permitirem obter soluções com um baixo número de más viragens sendo evitadas a quase totalidade das inversões de marcha proibidas. Muito embora a heurística se baseie na expansão da rede nos nodos onde as inversões de marcha não são permitidas, os resultados permitiram concluir que nem todos os nodos têm que ser expandidos para que as respectivas inversões de marcha sejam impossibilitadas.
Finding the optimal set of tours for vehicles dedicated to household refuse collection can be looked at as an are routing problem with additional constraints. Typically, the algorithms used in determining feasible solutions to these problems do not account for the type of turn that the vehicles actually must perform. Given the specifíc characteristics of the vehicles assigned to household refuse collection, a bad-turn translates to a U-turn or to a left-turn. In practical terms it is generally mandatory to minimize the total number of bad-turns, some of which really must be avoided either due to its intrinsic danger or to traffic regulation restrictions. Throughout this thesis the problem of minimizing the number of bad-turns is defmed and modeled as a network problem. Some methods are developed to determine feasible solutions. These methods have been tested over a set of randomly generated problems. It is shown that the overall results are to be considered pretty good since they represent feasible solutions with a very low number of bad-turns, where nearly every forbidden U-turns are avoided.

Full textEDF operates a large number of electrical rotating machines in its electricity generation capacity. Thermal stresses which affect them can cause local heating, sufficient to damage their integrity. The present work contributes to provide methodologies for detecting hot spots in these machines, better understanding the topology of rotating flows and identifying their effects on heat transfer. Several experimental scale model were used by increasing their complexity to understand and validate the numerical simulations. A first study on a turbulent wall jet over a non-confined backward-facing step (half-pole hydrogenerator) notes significant differences compared to results from confined case : both of them are present in an hydrogenerator. A second study was done on a small confined rotating scale model to determinate the effects of a Taylor-Couette-Poiseuille on temperature distribution and position of hot spots on the heated rotor, by studying the overall flow regimes flow. These studies have helped to obtain a reliable method based on conjugate heat transfer (CHT) simulations. Another method, based on FEM coupled with the use of an inverse method, has been studied on a large model of hydraulic generator so as to solve the computation time issue of the first methodology. It numerically calculates the convective heat transfer from temperature measurements, but depends on the availability of experimental data. This work has also developped new no-contact measurement techniques as the use of a high-frequency pyrometer which can be applied on rotating machines for monitoring temperature
