Great food, inspiring scientific discussions, and drinking sessions 🍻🙈

It was also my first time visiting Korea, and definitely not the last 🇰🇷✨

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 🙏 🙇‍♀️

+ 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 🎲🧮🇺🇦

It was also my first time visiting China, and it’s safe to say I’ll 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) 🎲🤖 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/

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 🧙‍♂️

Franziska Lesigang @franzilesi.bsky.social · Apr 6

How valuable is memory? In my very first paper, now published in Economics Letters, together with @chilbe.bsky.social and @nikoletaglyn.bsky.social, we give sufficient conditions under which a player can afford to remember less than their opponent. 🧵

Happy holidays everyone 🌨️ and here’s to a 2025 filled with cooperation, adaptability, and success! 🎇

What does this mean for real life? Success depends on balancing generosity, and adaptability. Cooperation works, but only when it aligns with the environment you’re in.

Nikoleta Glynatsi @nikoletaglyn.bsky.social · Dec 30

Strategies perform best when their level of cooperation matches the average “vibe” of the population. If most participants are cooperating, kindness wins. But in a tougher crowd, adaptability and cleverness are key. Context is everything.

Nikoleta Glynatsi @nikoletaglyn.bsky.social · Dec 30

1. Be Slightly Envious: Take advantage of naive opponents
2. Be Nice: Never defect first
3. Reciprocate: Retaliate in short tournaments but be forgiving in noisy settings
4. It's okay to be clever
5. Adapt: Align cooperation levels with the population’s average.

Nikoleta Glynatsi @nikoletaglyn.bsky.social · Dec 30

That’s where our work comes in. In our new study, we tested a massive collection of strategies across thousands of IPD tournaments—under more realistic conditions. Here’s what we found:

No single strategy dominates. Instead, the most successful strategies share common traits.

Nikoleta Glynatsi @nikoletaglyn.bsky.social · Dec 30

Axelrod’s tournament had some limitations🤔 For example, it relied on certain assumptions:

- A small pool of strategies
- Fixed game lengths
- No random noise (e.g., accidental betrayals)

This raised a big question: does Tit for Tat still work when things get more complex?
