Five Papers accepted at AAMAS

For the 22nd International Conference on Autonomous Agents and Multiagent Systems taking place in London from 29 May-2 June, three papers of our group were accepted. The first paper is the master thesis of new group member Michelle Döring titled Margin of Victory for Weighted Tournament Solutions. The Margin of Victory measures how close a winner of a tournament is to losing. The paper analysed its computability, structural behaviour and how it may be applied in praxis to ensure fairness and robustness of a tournament decision.

Together with researchers at the Royal Holloway University of London, George Skretas wrote the paper Being an Influencer is Hard: The Complexity of Influence Maximization in Temporal Graphs with a Fixed Source. Nowadays, marketing companies enlist influencers to market products on social media. After finding the appropriate influencer for each product, the company tasks the influencer with advertising it by posting on their social media account. But when is the optimal time to make a post? The authors use the temporal graphs model to find the optimal time for an influencer to make such posts depending on the viral strategy that the marketing company wants to follow.

Last, the paper Equilibria and Convergence in Fire Sale Games was written by Simon Krogmann and Pascal Lenzner in cooperation with researchers at the University of Frankfurt in the context of the ADYN research unit. In fire sales games agents try to minimize losses during fire sales, i.e., when financial assets are rapidly sold in the market causing a spiral of devaluation and further sales. The authors investigate the impact of a specific set of regulations and show that for some parameters easily reachable and socially good Nash equilibria always exist.

Additionally, the papers The Swiss Gambit and Single-Peaked Jump Schelling Games based on the master theses of Pascal Führlich and Lars Seifert were accepted as extended abstracts.
