The Association Computability in Europe (ACiE) is an international organization of mathematicians, logicians, computer scientists, philosophers, theoretical physicists and others interested in new developments in computability and in their underlying significance for the real world. ACiE aims to widen understanding and appreciation of the importance of the concepts and techniques of computability theory, and to support the development of a multi-disciplinary community of researchers focused on computability-related topics. The ACiE positions itself at the interface between applied and fundamental research, prioritising mathematical approaches to computational barriers.

ACiE originated as a research network called Computability in Europe (CiE) in 2003, became a conference series in 2005, and the ACiE was formed in 2008.

Association ACiE was founded in Athens, Greece in 2008. Its founding president (2008 to 2015) was S. Barry Cooper; its current president is Elvira Mayordomo and its current secretary general is Giuseppe Primiero. The association is promoting the development, particularly in Europe, of computability-related science, ranging over mathematics, computer science, and applications in various natural and engineering sciences such as physics and biology. This also includes the promotion of the study of philosophy and history of computing as it relates to questions of computability. ACiE is an international member of the Division for Logic, Methodology and Philosophy of Science and Technology of the International Union of History and Philosophy of Science (DLMPST/IUHPST).

Former members of the Council of the Association are: Alison Pease and Olivier Bournez (Past Membership Secretary).

Special Interest Groups The Association has three Special Interest Groups (SIGs): Women in Computability (WiC), Transfinite Computations (TraC), and History and Philosophy of Computing (HaPoC). SIGWiC has been organising the workshop Women in Computability at the CiE conferences since 2007; HaPoC also organizes two separate conference series: History and Philosophy of Computing and History and Philosophy of Programming.

S. Barry Cooper Prize In memory of the visionary engagement of its founding president, the association established the S. Barry Cooper Prize honouring a researcher who has contributed to a broad understanding and foundational study of computability by outstanding results, by seminal and lasting theory building, by exceptional service to the research communities involved, or by a combination of these. The inaugural S. Barry Cooper Prize was awarded in 2020 to Bruno Courcelle.

Conference series The association grew out of the major international conference series Computability in Europe (CiE); the first CiE conference was held in Amsterdam in June 2005. CiE is an interdisciplinary annual conference series promoting the development of computability-related science, ranging over mathematics, computer science, and applications in various natural and engineering sciences such as physics and biology. The conference scope also includes the study of philosophy and history of computing as it relates to questions of computability.
