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.
The study of matrices with a displacement structure is mainly concerned with recursions for the so-called generator matrices. The recursion usually involves free parameters, which can be chosen in several ways so as to simplify the resulting algorithm. In ...
This paper presents an evaluation of three software implementations of release consistency. Release consistent protocols allow data communication to be aggregated, and multiple writers to simultaneously modify a single page. We evaluated an eager invalidat ...
In dynamic graph algorithms the following provide-or-bound problem has to be solved quickly: Given a set S containing a subset R and a way of generating random elements from S testing for membership in R, either (i) provide an element of R, or (ii) give a ...
We model the problem of assigning referees to matches of volleyball championships as a combinatorial optimization problem. To solve it, we adapt three local search heuristics and study their behavior as a funtion of their parameters. We show the limitation ...
We study order preserving injections or bipartite matchings from poset V1 to poset V2. When V1 is totally ordered, we give an efficient algorithm for the associated optimization problem and the convex hull of the corresponding characteristic vectors. If V2 ...
This volume features twenty-one invited lectures presented at ismp97, the 16th International Symposium on Mathematical Programming, Lausanne EPFL. They reflect the unbroken vitality, creativity, and cross-disciplinarity that have characterized Mathematical ...
An algorithm that pre-computes a list of routes for each node in the network. An alternate route is also computed in case of overload of the primary one. Simulations show that this algorithm provides routes as good as On-Demand ones. ...
This paper describes algorithms for inserting monitoring code to profile and trace programs. These algorithms greatly reduce the cost of measuring programs with respect to the commonly used technique of placing code in each basic block. Program profiling c ...
In this paper, we investigate the applicability of backtrack technique for solving the vertex enumeration problem and the face enumeration problem for a convex polyhedron given by a system of linear inequalities. We show that there is a linear-time backtra ...
The authors formalize the description of the buffer-constrained adaptive quantization problem. For a given set of admissible quantizers used to code a discrete nonstationary signal sequence in a buffer-constrained environment, they formulate the optimal so ...
