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.

On Effect Analysis for Programs with Callbacks

Viktor Kuncak, Etienne Kneuss, Philippe Paul Henri Suter

We introduce a precise interprocedural effect analysis for programs with mutable state, dynamic object allocation, and dynamic dispatch. Our analysis is precise even in the presence of dynamic dispatch where the context-insensitive estimate on the number o ...

Cement and Concrete Research

Paul Bowen, Sandra Caroline Galmarini, Nicolas Ruffray

Experimental work has been done to determine changes in the particle shape of portlandite grown in the presence of different ions. To quantify the experimentally observed changes in morphology a new analysis tool was developed, allowing the calculation of ...

Towards Unbiased BFS Sampling

Patrick Thiran, Maciej Kurant

Breadth First Search (BFS) is a widely used approach for sampling large graphs. However, it has been empirically observed that BFS sampling is biased toward high-degree nodes, which may strongly affect the measurement results. In this paper, we quantify an ...

Goto Statement Considered Harmful – A Paper Review

In 1968 Edsger Dijkstra wrote a letter to the editor of Communications of the ACM (CACM) stating his opinion about using the goto statement in programs. This letter would serve to begin a hot-headed debate within the programming community. This topic, howe ...

Software Verification by Combining Program Analyses of Adjustable Precision

Grégory Théoduloz

In automatic software verification, we have observed a theoretical convergence of model checking and program analysis. In practice, however, model checkers, on one hand, are still mostly concerned with precision, e.g., the removal of spurious counterexampl ...

Stochastic Optimization of Sailing Trajectories in an America's Cup Race

Frédéric Dumas

The main objective of the thesis is the study and the determination of an optimal navigation strategy, for a sailboat in an America's Cup race, by methods of stochastic optimization. Such methods are appropriate because the sailing team expects the wind to ...

Querypoint Debugging

Claude Petitpierre, Salman Mirghasemi

To fix a bug, software developers have to examine the bug-gy execution to locate defects. They employ different ap-proaches (e.g., setting breakpoints, inserting printing statements in the code) to navigate over buggy execution and inspect program state at ...

On Locality of One-Variable Axioms and Piecewise Combinations

Viktor Kuncak, Swen Jacobs

Local theory extensions provide a complete and efficient way for reasoning about satisfiability of certain kinds of universally quantified formulas modulo a background theory. They are therefore useful in automated reasoning, software verification, and syn ...

Finding Loop Invariants for Programs over Arrays Using a Theorem Prover

Laura Ildiko Kovacs

We present a new method for automatic generation of loop invariants for programs containing arrays. Unlike all previously known methods, our method allows one to generate first-order invariants containing alternations of quantifiers. The method is based on ...
