Extended abstracts (1-2 pages) of original work should be submitted in pdf format.
========================================================
CCC is a workshop series that brings together researchers applying logical methods to the development of algorithms, with a particular focus on computation with infinite data, where issues of continuity, computability and constructivity play major roles. Specific topics include exact real number computation, computable analysis, effective descriptive set theory, constructive analysis, and related areas. The overall aim is to apply logical methods in these disciplines to provide a sound foundation for obtaining exact and provably correct algorithms for computations with real numbers and other continuous data, which are of increasing importance in safety critical applications and scientific computation.
Previous workshops have been held in Cologne 2009, Trier 2012, Gregynog 2013,
