Strategy logic

We introduce strategy logic, a logic that treats strategies in two-player games as explicit first-order objects. The explicit treatment of strategies allows us to specify properties of nonzero-sum games in a simple and natural way. We show that the one-alt ...

Mutual fund competition in the presence of dynamic flows

Julien Hugonnier

This paper analyzes competition between mutual funds in a multiple funds version of the model of Hugonnier and Kaniel (2010). We characterize the set of equilibria for this portfolio management game and show that there exists a unique Pareto optimal equili ...

A Hamilton-Jacobi Formulation for Cooperative Control of Multi-Agent Systems

Denis Gillet, Sylvain Rudaz, Hajir Roozbehani

Coordination of autonomous non-point agents is studied in this work. Interactions between vehicles together with their internal dynamics have been modeled as a continuous, unconstrained differential game. In particular, collision prediction is shown to be ...

Ambush avoidance in Vehicle Routing for valuable delivery

Matteo Salani, Gaëtan Duyckaerts, Peter Swartz

In this work we consider route planning for valuable delivery in an urban environment under the threat of ambushes in which a vehicle, starting from a depot, has to serve a set of predetermined destinations during the day. We provide a method to plan for h ...

Towards system optimum: Finding optimal routing strategies in time dependent networks for large-scale evacuation problems

Gunnar Flötteröd

Disaster and evacuation planning crucially depend on good routing strategies. This article compares two different routing strategies in a multi-agent simulation of a large real world evacuation scenario. The first approach approximates a Nash equilibrium w ...

On Non-cooperative Location Privacy: A Game-theoretic Analysis

Jean-Pierre Hubaux, Julien Freudiger, David C. Parkes

In mobile networks, authentication is a required primitive of the majority of security protocols. However, an adversary can track the location of mobile nodes by monitoring pseudonyms used for authentication. A frequently proposed solution to protect locat ...

Game Theoretic Considerations for the Gaussian Multiple Access Channel

Bixio Rimoldi, Vojislav Gajic

We study the behavior of users in a classical Additive White Gaussian Noise Multiple Access Channel. We model users as rational entities whose only interest is to maximize their own communication rate, and we model their interaction as a noncooperative one ...

Border Games in Cellular Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj, Diego Dufour

In each country today, cellular networks operate on carefully separated frequency bands. This separation is imposed by the regulators of the given country to avoid interference between these networks. But, the separation is only valid within the borders of ...

Non-cooperative behavior in wireless networks

Mark Felegyhazi

Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...

Non-cooperative Multi-radio Channel Allocation in Wireless Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj, Shirin Saeedi Bidokhti

Channel allocation was extensively studied in the framework of cellular networks. But the emergence of new system concepts, such as cognitive radio systems, has brought this topic into the focus of research again. In this paper, we study in detail the prob ...

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.
