Scope & Topics

The 13th International Conference on Foundations of Computer Science & Artificial Intelligence (FCSAI 2026) is a premier global forum dedicated to advancing the theoretical, methodological, and foundational aspects of Computer Science and Artificial Intelligence. Building on the legacy of the CST conference series, FCSAI 2026 expands its scope to embrace the rapidly evolving landscape of AI, machine learning, and intelligent systems, while maintaining a strong commitment to the core principles of theoretical computer science.

The goal of FCSAI 2026 is to bring together researchers, practitioners, and innovators from academia and industry to deepen the understanding of modern computational foundations and intelligent technologies. The conference aims to foster collaboration across disciplines, promote rigorous scientific exchange, and highlight cutting edge developments that shape the future of computing and AI.

Authors are invited to contribute high quality research articles, case studies, survey papers, and industrial experiences that demonstrate significant advances in foundational computer science, artificial intelligence theory, and their emerging intersections.
