Klaus F. Steiner's scientific venturesWelcome to the homepage for my scientific interests and contributions!
Why this website? Well, I'm passionate about science. Around 1990 I studied biology and a bit of mathematics and philosophy here in Graz, Austria. For my diploma thesis, I modeled and simulated the song interactions of bushcrickets. Instead of doing a dissertation, however, I ended up in software development and I am still employed today. For several years now, I have also been running a small puzzle company together with my wife Karin. We have thus turned our shared enthusiasm for puzzles and brain games into a sideline.

The Good, the Bad and the Stochastic: How Living in Groups Innately Supports Cooperation (PDF)bioRxiv 2021.02.21.431661; doi: https://doi.org/10.1101/2021.02.21.431661
Abstract: Based on theoretical considerations and computer simulations, I show that living in groups brings advantages for cooperative traits through purely stochastic effects that result from the division of a population into groups. These advantages can be sufficient to compensate individual selection pressures that may be associated with the cooperative traits. In more complex agent-based simulation models, this effect combined with some migration between the groups leads to stable dynamic equilibria between cooperative and defective replicators in the population.
Computer simulations: As supplement, I created adapted HTML versions of the two multi-agent simulations used for the paper. They open in a separate tab or window and can be run direclty in the browser. Depending on your hardware, the simulations can be relatively slow or appear to be inactive for a few seconds, but they usually run correctly.

I also maintain the website Vinckensteiner Rätsel und Denkspiele with puzzles and brain teasers (mainly in German, but with portions in English and Spanish) and the evolution page for kids Evolution in Aktion (in German).
