The20th edition of the International Symposium on Scientific Computing, Computer Arithmetic, and Verified Numerical Computations (SCAN) was organised by Andreas Rauh and Marit Lahme (both affiliated with the Department of Computer Science of the University of Oldenburg) and Ekaterina Auer (University of Applied Sciences Wismar) from the 22nd to 26th of September 2025.
Around 50 international participants from the Czech Republic, France, Germany, Hungary, Japan, Poland, Switzerland, and the United States visited Oldenburg to exchange the latest developments in the fields of reliable computing, software engineering, and uncertainty quantification with applications in such wide and varied areas as robotics, control, structural and civil engineering, and signal processing.
Besides classical presentations, SCAN 2025 has also focused on promoting the research of young researchers (Masters' and PhD students) in the form of interactive poster sessions. Peer-reviewed papers based on the contributions presented at SCAN are planned to be published in the International Journal of Approximate Reasoning as well as in Acta Cybernetica. The scientific committee of SCAN has decided in its meeting that the next conference (SCAN 2027) will be held in Kitakyushu, Japan; SCAN 2029 is planned to be held in Krakow, Poland.

Around 50 international participants from the Czech Republic, France, Germany, Hungary, Japan, Poland, Switzerland and the United States travelled to Oldenburg to discuss the latest developments in the fields of dependable computing, software engineering and uncertainty quantification, with applications in very different areas such as robotics, control engineering, civil engineering and structural mechanics as well as signal processing.
In addition to classical lectures, SCAN 2025 emphasised the promotion of research by young scientists (master's and doctoral students) in the form of interactive poster presentations. Peer-reviewed papers based on the talks presented during SCAN will be published in the International Journal of Approximate Reasoning and in Acta Cybernetica. At its meeting, the SCAN Scientific Committee decided to organise the next conference (SCAN 2027) in Kitakyushu, Japan. SCAN 2029 will also be held in Krakow, Poland.
