Title: From Monopoly to Competition: When Do Optimal Contests Prevail?
Presenter: Prof. Ron Lavi (U. of Bath, UK)
Abstract: We study competition among simultaneous heterogeneous contest designers, allowing a large contest design space. Symmetric contestants choose a contest and each contest designer aims to maximize the contestants’ sum of efforts exerted in her contest. We show that optimal contests in the monopolistic setting (i.e., those that maximize the sum of efforts in a model with a single contest designer) form Pareto-optimal equilibria when contest designers compete. Under a natural assumption, monopolistic optimal contests are in fact dominant in the competitive case, and the equilibria they form are unique. In many natural cases, they also maximize the social welfare.

To position Greece as a leading player in AI and Data Science
To build an AI Excellence Hub in Greece where the international research community can connect, groundbreaking ideas can thrive, and the next generation of scientists emerges, shaping a brighter future for Greece and the world
Welcome to ARCHIMEDES, a vibrant research hub connecting the global AI and Data Science research community fostering groundbreaking research in Greece and beyond. Its dedicated core team, comprising lead researchers, affiliated researchers, Post-Docs, PhDs and interns, is committed to advancing basic and applied research in Artificial Intelligence and its supporting disciplines, including Algorithms, Statistics, Learning Theory, and Game Theory organized around 8 core research areas. By collaborating with Greek and Foreign Universities and Research Institutes, ARCHIMEDES disseminates its research findings fostering knowledge exchange and providing enriching opportunities for students. Leveraging AI to address real-world challenges, ARCHIMEDES promotes innovation within the Greek ecosystem and extends its societal impact. Established in January 2022, as a research unit of the Athena Research Center with support from the Committee Greece 2021, ARCHIMEDES is funded for its first four years by the EU Recovery and Resilience Facility (RRF).
First call for papers for the "Workshop on Dialects in NLP: A Resource Perspective" at the three-day Language Resources Association Conference (LREC) 2026. This workshopwill be held in conjunction with LREC 2026, Palma de Mallorca, Spain on 11, 12 and 16 May 2026. It is a hybrid event and attendance can be in person or online.
Archimedes Unit of the Athena Research Center, Greece, encourages participation in the "ELLIS Winter School 2026: AI for Earth System, Hazards, and Climate Extremes", taking place on March 16-20, 2026, at the National Technical University of Athens, Greece.
🌟 The Archimedes Community of the Athena Research Center, Greece, would like to wish everyone a Merry Christmas and a holiday season filled with happiness, gratitude, and good health. ✨
Vassilis Alimisis, a Postdoc at the Archimedes Unit of the Athena Research Center in Greece, a Collaborating Researcher at the School of Electrical and Computer Engineering at the National Technical University of Athens in Greece, an Adjunct Lecturer at the Department of Digital Industry Technologies at the National and Kapodistrian University of Athens in Greece, and a National Postdoctoral Research Fellow of the Bodossaki Foundation, Athens, Greece, will deliver a tutorial at the 2025 International Conference on Microelectronics (ICM), which will take place on 14-17 December 2025, in Cairo, Egypt.
The Preliminary Phase "Talos" of the Greek Olympiad in Artificial Intelligence (PDTN) is now open for online participation. This competition for middle and high school students will run from December 1, 2025 until March 1, 2026, and students will be asked to solve four problems: one on Decision Trees (Δεντρα Αποφασης), one on CAPTCHA Challenges (Επίλυση CAPTCHA), one for Emotion Classification (Συναισθηματα), and one on Movie Recommendation Systems (Επόμενη Ταινία).
The project “ARCHIMEDES Unit: Research in Artificial Intelligence, Data Science and Algorithms” with code OPS 5154714 is implemented by the National Recovery and Resilience Plan “Greece 2.0” and is funded by the European Union – NextGenerationEU.
