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.

Software verification and graph similarity for automated evaluation of students' assignments

Viktor Kuncak

Context: The number of students enrolled in universities at standard and on-line programming courses is rapidly increasing. This calls for automated evaluation of students assignments. Objective: We aim to develop methods and tools for objective and reljab ...

Functional synthesis for linear arithmetic and sets

Viktor Kuncak, Mikaël Mayer, Philippe Paul Henri Suter, Ruzica Piskac

Synthesis of program fragments from specifications can make programs easier to write and easier to reason about. To integrate synthesis into programming languages, synthesis algorithms should behave in a predictable way—they should succeed for a well-defin ...

On Software Verification and Graph Similarity for Automated Evaluation of Students' Assignments

Viktor Kuncak

The number of students enrolled in universities at standard and online programming courses is huge. This calls for automated evaluation of students assignments and for automated support for learning. We aim at developing methods and tools for objective and ...

Trustworthy Numerical Computation in Scala

Viktor Kuncak, Eva Darulova

Modern computing has adopted the floating point type as a default way to describe computations with real numbers. Thanks to dedicated hardware support, such computations are efficient on modern architectures. However, rigorous reasoning about the resulting ...

Generalized Universality

Rachid Guerraoui

State machine replication reduces distributed to centralized computing. Any sequential service, modeled by a state machine, can be replicated over any number of processes and made highly available to all of them. At the heart of this fundamental reduction ...

Online Testing of Federated and Heterogeneous Distributed Systems

Dejan Novakovic, Dejan Kostic, Marco Canini, Vojin Jovanovic

DiCE is a system for online testing of federated and heterogeneous distributed systems. We have built a prototype of DiCE and integrated it with a BGP router. DiCE quickly detects three important classes of faults, resulting from configuration mistakes, po ...

The VELOX Transactional Memory Stack

Rachid Guerraoui, Vincent Gramoli, Michal Kapalka, Aleksandar Dragojevic, Pascal Felber

The adoption of multi- and many-core architectures for mainstream computing undoubtedly brings profound changes in the way software is developed. In particular, the use of fine grained locking as the multi-core programmer’s coordination methodology is cons ...

On Complete Functional Synthesis

Viktor Kuncak, Mikaël Mayer, Philippe Paul Henri Suter, Ruzica Piskac

Distributed Consensus, Revisited

Rachele Fuzzati, Massimo Merro

We provide a novel model to formalize a well-known algorithm, by Chandra and Toueg, that solves Consensus among asynchronous distributed processes in the presence of a particular class of failure detectors (Diamond S or, equivalently, Omega), under the hyp ...

Singularity: Rethinking the Software Stack

James Richard Larus

Every operating system embodies a collection of design decisions. Many of the decisions behind today's most popular operating systems have remained unchanged, even as hardware and software have evolved. Operating systems form the foundation of almost every ...
