● του Βραβείου Καλύτερης Διδακτορικής Διατριβής ΕΕΤΝ 2025 στον κ. Γεώργιο Παπασωτηρόπουλο (χρηματικό βραβείο 1.000 Ευρώ και δωρεάν συμμετοχή στο ΣΕΤΝ 2026)

(“Algorithmic and Game-theoretic Aspects of Computational Social Choice”, Τμήμα Πληροφορικής, Οικονομικό Πανεπιστήμιο Αθηνών, επιβλέποντας καθ. Ευάγγελος Μαρκάκης). 

“The dissertation of Mr Papasotiropoulos, situated in the field of computational social choice, makes timely and significant contributions to the analysis of election rules in voting theory. He provides theoretical insights into the complexity of elections with conditional preferences, the vulnerability of such elections to adversarial manipulation, and the impact of conditional preferences on the proportional representation. Furthermore, he introduces innovative approximation algorithms and models for proxy voting and liquid democracy. This includes addressing optimal vote delegation for social welfare, modeling deliberation phases where voters update their opinions, and accounting for scenarios involving incomplete preferences.

The impact and technical quality of this thesis are evidenced by its publication record in top-tier AI venues (including 3 IJCAI papers, AAMAS, ADT, SAGT, and Theoretical Computer Science) and its strong citation count. Ultimately, we believe this research holds profound potential for application in the broader domains of Economics and Democracy.”
