32nd International Colloquium on Structural Information and Communication Complexity (SIROCCO 2025)

The 32nd International Colloquium on Structural Information and Communication Complexity (SIROCCO 2025) took place on June 2-4, 2025 at the European Cultural Centre of Delphi, gathering more than 50 participants from across the globe in the historic town of Delphi, Greece. The conference featured three distinguished keynote speakers: Hagit Attiya (Technion, Israel), Joseph Y. Halpern (Cornell University, USA), and Christos Papadimitriou (Columbia University, USA & Archimedes AI, Greece). SIROCCO 2025 awarded the Prize for Innovation in Distributed Computing to Sergio Rajsbaum (UNAM, Mexico) for his pioneering work in the theory of distributed systems. The program included 24 original research papers and 4 brief announcements, selected through a competitive single-blind peer-review process. Topics included distributed algorithms, structural complexity, networked computation, fault tolerance, and epistemic logic. SIROCCO 2025 maintained its long-standing tradition of scientific excellence in an informal and collaborative setting. The event was co-organized by the ATHENA Research Center (Archimedes Unit) and the University of Ioannina, with principal support from Toronto Metropolitan University, Department of Mathematics and the Faculty of Science.
