🗞 Complex social systems simulations – human behavior modeling, lecture on Friday at Auditorium Maximum
I will be talking about how challenging is introducing the human factor into models and simulations considering humans have their unpredictability and free will what makes simulations more complex. The main question is how do we incorporate these aspects into modeling. Together with the audience I will go on a journey through various examples, from road traffic to pedestrian traffic simulations, presenting how human decisions can shape social phenomena. Finally, I will show how to use artificial intelligence in simulations where people compete for limited resources with intelligent machines.
See you there!

| Mar 13, 2024 | Young blood at the Faculty of Mathematics and Computer Science during the 16th edition of the Faculty Day! So many inspiring lectures, fruitful discussions and workshops including mine conducted together with Zoltán Varga. Complex social systems simulation at the example of road traffic occured to be very vivid theme for all participants. Such brainstorming atmosphere urges us for further action. I am very proud I could be the part of this initiative. Let me take you there |
| Feb 28, 2024 | Great honour to meet with the Jagiellonian University Representatives and my colleagues from other faculties, who also run ERC grants. I talked about the progress in my COeXISTENCE grant, future plans and challenges. Check out more here |

Such a wonderful evening at #Krakow’s Kazimierz. Not only a Christmas Party, but also the first time when the complete team of #ERC #COeXISTENCE had a chance to meet and integrate with themselves as well as with ‘older’ friends.
👐 Ten brilliant minds, working now at Jagiellonian University to contribute towards future urban mobility. Great pride of you, wish all the best in the coming year!

🗞 When ride-pooling is attractive/efficient for all the parties involved (passengers, platforms/providers, city/environment/sustainability)?
We examined half a year (1.5 million trip sample) from NYC, run 9 000 experiments with our 𝐄𝐱𝐌𝐀𝐒 and report 6 KPIs to move beyond the well-known 𝐜𝐫𝐢𝐭𝐢𝐜𝐚𝐥 𝐦𝐚𝐬𝐬 and better understand ride-pooling potential.
See our results in 𝐉𝐨𝐮𝐫𝐧𝐚𝐥 𝐨𝐟 𝐓𝐫𝐚𝐧𝐬𝐩𝐨𝐫𝐭 𝐆𝐞𝐨𝐠𝐫𝐚𝐩𝐡𝐲: https://lnkd.in/dW5hBvhC or: https://lnkd.in/dGWVbjGN with Olha Shulika Michał Bujak and Farnoud Ghasemi

| Jan 20, 2020 | Yesterday Guido Cantelmo (TUM) presented our poster on big mobility data in Washington at #TRBAM. We collected data on millions of city bike trips from NYC and started thinking how to synthesize them. We came up with this idea of ‘vector of movement’ that aggregates mobility pattern into a single vector. With this we may now cluster big datasets into groups of similar patterns and provide more accurate mobility predictions (including weather). |
