Long time, no see: Virtual Lunch Roulette
Abstract: When distributing individuals into groups every week for a virtual social mixer, e.g. using Zoom breakout rooms, it’s boring to end up in a group with someone, who you already met last week. We compute the probility for this to happen and state a simple rejection sampling proposal for how to increase social diversity in such grouping...

An R Package for Social Roulette
Abstract: We introduce the R package socialroulette, which is a lightweight package for handling the recurrent problem of assigning individuals into groups of a fixed size. In order to minimize reunions, we provide an algorithm to solve the task as an instance of the maximally diverse grouping problem. This work is licensed under a Creative Co...
