This week I got to return to Cardiff University ๐ด๓ ง๓ ข๓ ท๓ ฌ๓ ณ๓ ฟ where I completed my PhD, to present some of my current research ๐
It was good to visit my former department (now in a new building) and share how my work has changed since my doctoral studies! ๐๐ฒ
Thank you @ignat1.bsky.social for inviting me to contribute!

A huge present for my small contribution at the Game Theory Summer School in Kyiv arrived today! ๐
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 ๐
Our framework offers a rigorous foundation for understanding how social norms evolve and persist, even when people sometimes misjudge, act randomly, or punish at a cost.
It unifies earlier results and opens the door to studying robust cooperation in complex societies.
๐งต (6/6)
Some of these norms are especially interesting: they fix the payoff of any mutant strategy, similar to zero-determinant strategies in direct reciprocity (Press & Dyson 2012).
๐งต (5/6)
In our new work, we analytically characterize all stable norms under public assessment.
โ
We recover the known cooperative norms
โ
We extend to cases with errors and costly punishment
โ
And we discover new, more general stable norms
๐งต (4/6)
Previous studies found a few โgoodโ norms (like the famous leading eight) that can sustain cooperation.
But we still lacked a complete analytical characterization of all evolutionarily stable norms, especially when actions or judgments are noisy, or when punishment is possible.
๐งต (3/6)
Indirect reciprocity means:
๐ I help you,
๐ others see that,
๐ and later, someone else helps me.
This works only if society shares a norm about who deserves help. These norms link actions to reputations, and reputations to future treatment.
๐งต (2/6)
๐๏ธ๐ฃ 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 ๐ฃ๏ธ But which social norms make this stable, even when mistakes happen?

๐ #ICSD2026 is on!
Great meeting, amazing location, and an even cooler logo! ๐
Join us in Shimonoseki, Japan! ๐ฏ๐ต
Great food, inspiring scientific discussions, and drinking sessions ๐ป๐
It was also my first time visiting Korea, and definitely not the last ๐ฐ๐ทโจ

Attended my first RHINO conference (APCTP Workshop on the Roles of Heterogeneity in Nonequilibrium) this weekend ๐ 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 ๐ ๐โโ๏ธ
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.

If you're curious about my talk, the materials are available on GitHub: github.com/Nikoleta-v3/... ๐
+ 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 ๐ฒ๐งฎ๐บ๐ฆ
It was also my first time visiting China, and itโs safe to say Iโll be going back soon!
Here are a few random pictures from Hangzhou and Beijing.
Last week, I had the pleasure of attending EGAI (Game Theory & Artificial Intelligence Conference) ๐ฒ๐ค as an invited speaker. This conference is becoming the main event for bringing together the game theory community in ๐จ๐ณ 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! ๐ฐ๐ 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! ๐ฏ๐ต๐
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 ๐งต๐
This is my first last-author publication! Feeling like a wise person already ๐งโโ๏ธ
Thank you Diogo ๐๐ป๐ฅณ
A great summary of our recent articles, now live here ๐ The work was conducted at the MPI for Evolutionary Biology๐ง๐ปโ๐ฌ Check it out to learn more about game theory and cooperation ๐ค
Hahaha my moment of fame! Thank you for sharing ๐๐ปโบ๏ธ
Thank you ๐
Thank you very much Catherine! ๐๐ป
Thank you! Looking forward to inviting you here soon ๐๐๐ป
I am very grateful to @chilbe.bsky.social and the DYNOSOBs group for the past four years! I will remain an external member of the group, a nice way to still being able to enjoy the perks of the group! ๐ ๐ฆ
For those in the social behavior, cooperation, and game theory circles, you have probably heard of this team due to the amazing work done here by @yohm.bsky.social ๐ค
