Two papers accepted at IJCAI

We are happy to announce that two papers written by members of our group have been accepted for publication at the International Joint Conference on Artificial Intelligence (IJCAI 2022). It is a prime venue for research in AI and leading the way both for novel techniques as well as new application domains. The first paper Tolerance is Necessary for Stability: Single-Peaked Swap Schelling Games written by Pascal Lenzner and Louise Molitor in collaboration with Davide Bilò (University of L’Aquila) and Vittorio Bilò (University of Salento) addresses sociological polls suggesting that in contrast to earlier models of residential segregation, real-world agents favor mixed-type neighborhoods. To address this, they studied Schelling games with single-peaked utilities and showed that tolerance is necessary for equilibrium existence.

In the second paper Network Creation with Homophilic Agents, Pascal Lenzner and Anna Melnichenko together with Martin Bullinger (TU Munich) study Network Creation Games with multiple types of homophilic agents and nonuniform edge cost, introducing two models focusing on the perception of same-type and different-type neighboring agents, respectively. Their theoretical and experimental analysis show that both the composition and segregation strength of the resulting stable networks are almost identical, indicating a robust structure of social networks under homophily.
