Full textThe theory of NP-completeness tells us that for many optimization problems, there is no hope for finding an efficient algorithm computing an optimal solution. Based on this, two classical approaches have been developped to deal with these problems. The first one, called polynomial- time approximation, consists in designing efficient algorithms computing a solution that is close to an optimal one. The second one, called param- eterized complexity, consists in designing exact algorithms which com- binatorial explosion is captured by a carefully chosen parameter of the instance. The goal of this thesis is twofold. First, we study and apply classical methods from these two domains in order to obtain positive and negative results for two optimization problems in graphs: a partitioning problem called Sparsest k-Compaction, and a cardinality constraint subgraph problem called Sparsest k-Subgraph. Then, we present how the different methods from these two domains have been combined in recent years in a concept called parameterized approximation. In particular, we study the links between approximation and kernelization algorithms

Full textThe objective of this work consists on the realization of a dynamic guidance system in a multimodal network for users equipped with an information device while taking into account users that are not equipped with such devices. The work is organized into parts: a conception part and a theoretical study part. The conception part consists on the development of the guidance tool using a multi agent architecture. This tool assists users in their daily travels by giving them the itinerary that suits best not only their needs but also the overall network. The theoretical study emphasizes on how the performance of the network can be enhanced. To do so, three main studies will be presented: the impact of the information on the cost of the itineraries, the impact of the reorientation of users towards transportation systems on the road network and finally the benefits of introducing autonomous vehicles

Full textThis thesis proposes to evaluate XQuery queries into a mediation context. This mediator must federate several heterogeneous data sources with an appropriate query model. On this model, an optimization framework must be defined to increase performance. The well-known tree pattern model can represent a subset of XPath queries in a tree form. Because of the complexity of XQuery, no model has been proposed that is able to represent all the structural components of the language. Then, we propose a new logical model for XQuery queries called TGV. It aims at supporting the whole XQuery into a canonical form in order to check more XQuery specifications. This form allows us to translate in a unique way queries into our TGV model. This model takes into account a distributed heterogenous context and eases the optimization process. It integrates transformation rules, cost evaluation, and therefore, execution of XQuery queries. The TGV can be used as a basis for processing XQuery queries, since it is flexible, it provides abstracts data types wich can be implemented according to the underneath data model. Moreover, it allows user-defined annotating ans also cost-related annotating for cost estimation. Althouogh the model will be useful, it relies on XQuery complicates specifications. TGV are illustrated in this thesis with several figures on W3C's uses cases. Finally, a framework to define transformation rules is added to the extensible optimizer to increase the XLive mediator performances. The XLive mediation system has been developped at the PRISM laboratory

Full textThis thesis concerns the study of the algorithmic and the complexity of the communication in radio networks. In particular, we were interested in the problem of gathering information from the nodes of a radio network in a central node. This problem is motivated by a question of France Telecom (Orange Labs) “How to bring Internet in villages”. Nodes represent the houses of the villages which communicate between them by radio, the goal being to reach a gateway connected to Internet by a satellite link. The same problem can be found in sensor networks where the question is to collect data from sensors to a base station. A peculiarity of radio networks is that the transmission distance is limited and that the transmissions interfere between them (interference phenomena). We model these constraints by saying that two nodes (radio devices) can communicate if they are at distance at most dT and a node interferes with another one if their distance is at most dI. The distances are considered in a graph representing the network. Thus, a communication step will consist in a compatible (non interfering) set of transmissions. Our goal is to find the minimum number of steps needed to achieve such a gathering and design algorithms achieving this minimum. For special topologies such as the path and the grid, we have proposed optimal or near optimal solutions. We also considered the systolic (or continuous) case where we want to maximize the throughput (bandwidth) offered to each node

Full textThe discovery of novel gene regulatory processes improves the understanding of cell phenotypicresponses to external stimuli for many biological applications, such as medicine, environmentor biotechnologies. To this purpose, transcriptomic data are generated and analyzed from mi-croarrays or more recently RNAseq experiments. For each gene of a studied organism placed indifferent living conditions, they consist in a sequence of genetic expression levels. From thesedata, gene regulation mechanisms can be recovered by revealing topological links encoded ingeometric graphs. In regulatory graphs, nodes correspond to genes. A link between two nodesis identified if a regulation relationship exists between the two corresponding genes. Such net-works are called Gene Regulatory Networks (GRNs). Their construction as well as their analysisremain challenging despite the large number of available inference methods.In this thesis, we propose to address this network inference problem with recently developedtechniques pertaining to graph optimization. Given all the pairwise gene regulation informa-tion available, we propose to determine the presence of edges in the final GRN by adoptingan energy optimization formulation integrating additional constraints. Either biological (infor-mation about gene interactions) or structural (information about node connectivity) a priorihave been considered to reduce the space of possible solutions. Different priors lead to differentproperties of the global cost function, for which various optimization strategies can be applied.The post-processing network refinements we proposed led to a software suite named BRANE for“Biologically-Related A priori for Network Enhancement”. For each of the proposed methodsBRANE Cut, BRANE Relax and BRANE Clust, our contributions are threefold: a priori-based for-mulation, design of the optimization strategy and validation (numerical and/or biological) onbenchmark datasets.In a ramification of this thesis, we slide from graph inference to more generic data processingsuch as inverse problems. We notably invest in HOGMep, a Bayesian-based approach using aVariation Bayesian Approximation framework for its resolution. This approach allows to jointlyperform reconstruction and clustering/segmentation tasks on multi-component data (for instancesignals or images). Its performance in a color image deconvolution context demonstrates bothquality of reconstruction and segmentation. A preliminary study in a medical data classificationcontext linking genotype and phenotype yields promising results for forthcoming bioinformaticsadaptations
