A huge present for my small contribution at the Game Theory Summer School in Kyiv arrived today! 🎁

The school was jointly organised by the Kyiv School of Economics and the Ukrainian Catholic University. The main work was carried out by the local organisers, who put together an excellent programme 🙏

🗞️📣 New paper "Exact conditions for evolutionary stability in indirect reciprocity under noise" with @chilbe.bsky.social & @yohm.bsky.social

How can cooperation persist in large groups of unrelated individuals? Reputation 🗣️ But which social norms make this stable, even when mistakes happen?

🌏 #ICSD2026 is on!
Great meeting, amazing location, and an even cooler logo! 😄
Join us in Shimonoseki, Japan! 🇯🇵

Attended my first RHINO conference (APCTP Workshop on the Roles of Heterogeneity in Nonequilibrium) this weekend 🎉 where I had the pleasure of giving an invited talk.

The event was held at Pukyong National University, Busan, & was wonderfully organized by Seung Ki Baek + Eun Lee 🙏 🙇‍♀️

We're organizing the "APCTP Workshop on the Roles of Heterogeneity in Nonequilibrium (RHINO 2025)"; the workshop will be held from 29 August to 1 September 2025 in Pukyong National University (PKNU), Busan, Korea.

+ Yesterday, I gave a lecture on computational approaches to game theory at a summer school in Kyiv. You can find more information about the summer school, and a very impressive list of speakers, here: game-theory-school.kse.ua 🎲🧮🇺🇦

Last week, I had the pleasure of attending EGAI (Game Theory & Artificial Intelligence Conference) 🎲🤖 as an invited speaker. This conference is becoming the main event for bringing together the game theory community in 🇨🇳 I wrote a short post about the conference here: nikoleta-v3.github.io/egai/

Just published in JOSS: 'HeXtractor: Extracting Heterogeneous Graphs from Structured and Textual Data for Graph Neural Networks' https://doi.org/10.21105/joss.08057

An incredible opportunity! 📰🎉 Join our research group exploring social questions, work with an amazing supervisor, and live in Japan for a few years while you're at it! 🇯🇵🍜

Some amazing work by @franzilesi.bsky.social on repeated games! In this new paper, she describes the conditions under which a player can remember less than their opponent and still achieve a best response. See 🧵👇

This is my first last-author publication! Feeling like a wise person already 🧙‍♂️

A great summary of our recent articles, now live here 👇 The work was conducted at the MPI for Evolutionary Biology🧑🏻‍🔬 Check it out to learn more about game theory and cooperation 🤝

I am genuinely very excited to announce that I am officially a Research Scientist at the RIKEN Center for Computational Science in the Discrete Event Simulation team, led by Nobuyasu Ito! 🇯🇵 🗾 🗻

Looking for a light read during the holidays?🎄 Let me tell you about our new publication with Vince Knight & @marcharper.bsky.social on the properties of strategies in computer tournaments for the Iterated Prisoner’s Dilemma (IPD) 🧵

A very nice journey with a great ending: In a new paper, @NikoletaGlyn describes how longer memory allows people to sustain reciprocal cooperation. For details, see 🧵 below 👇
Paper: www.pnas.org/doi/10.1073/...

Cooperation in society:
How our memory influences our behavior

Conditional cooperation with longer memory 🏺🧪

Direct reciprocity is based on repeated interactions. Nice strategies are never the first to defect which can sustain full cooperation as a Nash equilibrium.

🚨Together with Ethan Akin, Martin A Nowak and @chilbe.bsky.social our new paper published in PNAS characterizes partner strategies (Nash strategies that sustain cooperation) for reactive-n strategies in repeated games 🧵

There seem to be a lot of BlueSky users interested in evolutionary game theory and related areas of theoretical ecology and evolution.

I made a preliminary starter pack for EGT and related topics. Please let me know if you would like to join or if you have any suggestions.
