F.A.Z. Digitec Podcast 13 May 2023

The most recent edition of the digitec podcast (in German) of Frankfurter Allgemeine Zeitung features an interview with Martin Hoefer and Sebastian Faust on the impact of blockchain, algorithms, and AI.

Two Papers at IJCAI 2023 19 Apr 2023

Two papers of our group were accepted as full papers at the 32nd International Joint Conference on Artificial Intelligence (IJCAI 2023), one of the two international top conferences in artificial intelligence:

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:

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

Thanks to all the participants who made our Dagstuhl seminar on Computational Social Dynamics such an enjoyable and extremely productive event.

Invited Talk 29 Jul 2022

Martin Hoefer will give an invited talk at the 12th Days on Computational Game Theory on Sep 29/30, 2022 at University of Bremen.

Welcome 1 Jul 2022

Our former secretary Jutta Nadland retired on June 30. We thank her for the many contributions to our team and the excellent service, and we wish her all the best!
At the same time, we welcome Marta Soares as the new secretary in our group.

New Paper at SAGT 2022 1 July 2022

Our paper ''Seniorities and Minimal Clearing in Financial Network Games'' (by Martin Hoefer, Lisa Wilhelmi) was accepted at the 15th Int. Symposium on Algorithmic Game Theory (SAGT 2022).

Graduation Awards 30 Jun 2022

Several (former) members of our group received awards for oustanding performances among the 2021/22 graduates in Computer Science at Goethe University:

Congratulations to all of them, well deserved!

New Paper at EC 2022 9 May 2022

Our paper ''Public Signals in Network Congestion Games'' (by Svenja Griesbach, Martin Hoefer, Max Klimm, Tim Koglin) was accepted at the 23rd ACM Conference on Economics and Computation (EC 2022), the international top conference at the intersection of computer science and economics.

Thesis Defense 27 Apr 2022

Niklas Hahn successfully defended his thesis entitled Algorithms for Bayesian Persuasion and Delegated Search. Starting in May 2022 he will be a postdoc in the RO team of the LIP6 lab at Sorbonne University.
Congratulations to Dr. Hahn!
