Rumour Spreading Depends on the Latent Geometry and Degree Distribution in Social Network Models
Marc Kaufmann, Kostas Lakis, Johannes Lengler +3
We study push-pull rumour spreading in ultra-small-world models for social networks where the degrees follow a power-law distribution. In a non-geometric setting, Fountoulakis, Pan…

Expanders in Models of Social Networks
Marc Kaufmann, Johannes Lengler, Ulysse Schaller +1
A common model for social networks are Geometric Inhomogeneous Random Graphs (GIRGs), in which vertices draw a random position in some latent geometric space, and the probability o…

Self-Adjusting Evolutionary Algorithms Are Slow on Multimodal Landscapes
Johannes Lengler, Konstantin Sturm
The one-fifth rule and its generalizations are a classical parameter control mechanism in discrete domains. They have also been transferred to control the offspring population size…
