Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Networked Slepian-Wolf: Theory and Algorithms

Martin Vetterli, Razvan Cristescu

In this paper, we consider the minimization of a relevant energy consumption related cost function in the context of sensor networks where correlated sources are generated at various sets of source nodes and have to be transmitted to some set of sink nodes ...

Genomic distances under deletions and insertions

Bernard Moret, Krister Swenson

As more and more genomes are sequenced, evolutionary biologists are becoming increasingly interested in evolution at the level of whole genomes, in scenarios in which the genome evolves through insertions, deletions, and movements of genes along its chromo ...

Using the Breakout Algorithm to Identify Hard and Unsolvable Subproblems

Boi Faltings, Carlos Eisenberg

Local search algorithms have been very successful for solving constraint satisfaction problems (CSP). However, a major weakness has been that local search is unable to detect unsolvability and is thus not suitable for highly constrained or overconstrained ...

A polynomial case of inconstrained zero-one queadratic optimization

Thomas Liebling, Kim Alexandre Allemand

Unconstrained zero-one quadratic maximization problems can be solved in polynomial time when the symmetric matrix describing the objective function is positive semidefinite of fixed rank with known spectral decomposition. ...

Maintaining minimum spanning forests in dynamic graphs

Monika Henzinger

We present the first fully dynamic algorithm for maintaining a minimum spanning forest in time o(sqrt(n)) per operation. To be precise, the algorithm uses O(n1/3 log n) amortized time per update operation. The algorithm is fairly simple and deterministic. ...

Cocircuit Graphs and Efficient Orientation Reconstruction in Oriented Matroids

We consider the cocircuit graph GM of an oriented matroid M, which is the 1-skeleton of the cell complex formed by the span of the cocircuits of M. As a result of Cordovil, Fukuda, and Guedes de Oliveira, the isomorphism class of M is not determined by GM, ...

An efficient Fault Localization Algorithm for IP/WDM Networks

Patrick Thiran, Carmen Mas

We propose an algorithm for localizing multiple failures in an IP/WDM network. They can be either hard failures (unexpected events that interrupt suddenly the established channels) or soft failures (events that progressively degrade the quality of transmis ...

List decoding of algebraic geometric codes

Mohammad Amin Shokrollahi

We generalize Sudan's (see J. Compl., vol.13, p.180-93, 1997) results for Reed- Solomon codes to the class of algebraic-geometric codes, designing algorithms for list decoding of algebraic geometric codes which can decode beyond the conventional error-corr ...

Scheduling multicasts on unit-capacity trees and meshes

Monika Henzinger

This paper studies the multicast routing and admission control problem on unit-capacity tree and mesh topologies in the throughput-model. The problem is a generalization of the edge-disjoint paths problem and is NP-hard both on trees and meshes. We study b ...
