DFG Grant 31 Jan 2023
In a new three-year project Online Algorithms for Bayesian Persuasion funded by the German Research Foundation, we study algorithmic problems for signaling and persuasion. These problems arise among agents with asymmetric information in the context of many economic applications, e.g., product recommendations, consulting, and more. An algorithmic challenge we tackle in the project are online scenarios, in which information is revealed sequentially to the informed agent(s). The project is a cooperation with Rann Smorodinsky from the Technion.
Two Papers at AAMAS 2023 4 Jan 2023
Two papers of our group were accepted as full papers at the 22nd International Conference on Autonomous Agents and Multiagent Systems (AAMAS 2023), the international top conference on multiagent systems:
- Equilibria and Convergence in Fire-Sale Games
(by Nils Bertschinger, Martin Hoefer, Simon Krogmann, Pascal Lenzner, Steffen Schuldenzucker, Lisa Wilhelmi) - Best of Both Worlds: Agents with Entitlements
(by Martin Hoefer, Giovanna Varricchio, Marco Schmalhofer)
ATHENE Grant on Decentralized Exchanges 29 Nov 2022
In a new four-year project Cryptography and Game Theory for Decentralized Exchanges funded within the ATHENE Center for Applied Cybersecurity, we study algorithmic and economic aspects of decentralized exchanges (DEXes). An intriguing innovation of DEXes is the automated market maker (AMM), a smart contract running on a blockchain that manages a pool of assets and executes trades using a carefully designed exchange mechanism. Our main goal is to understand and improve the algorithmic, economic, and security aspects of this technology. The project is a joint effort with Sebastian Faust from TU Darmstadt.
New Paper at AAAI 2023 20 Nov 2022
Our paper ''PAC Learning and Stabilizing Hedonic Games: Towards a Unifying Approach'' (by Simone Fioravanti, Michele Flammini, Bojana Kodric, Giovanna Varricchio) was accepted at the 37th AAAI Conference on Artificial Intelligence (AAAI 2023), one of the two international top conferences in artificial intelligence.
Dagstuhl Seminar 11 Nov 2023
