Description
SWAT studies software systems: their design, construction and evolution. Our mission is to learn to understand software systems and to improve their quality. In particular, we study the causes of software complexity – a major cause of technology failure in society – and investigate how complex systems can be made simpler and more reliable. We analyze and visualize software systems, transforming them into better versions of themselves. We also generate new software with the goal of simplifying it through automation and abstraction. We keep our feet on the ground by working with corporate IT departments on streamlining their software systems and making them more reliable. Putting our ideas into practice is the best way to ensure they work.

CWI RESEARCHERS DEVELOP NEW TECHNIQUES FOR GENERAL TOP-DOWN PARSING OF PROGRAMMING LANGUAGES
Afroozeh and Izmaylova, PhD students at CWI's Software Analysis and Transformation group, present new techniques for declarative parsing of programming languages in their thesis "Practical Genereal Top-down Parsers."

New insights from reconstructing the first ALGOL 60 system
Gauthier van den Hove (CWI) reconstructed and analyzed the first ALGOL 60 system, a computer system designed and implemented at the Mathematical Centre (MC), now CWI. On 15 February he defends his PhD thesis, which has a foreword written by the famous computer science pioneer Donald Knuth.

CWI develops new techniques for modular programming languages
The development of domain specific languages requires highly specialized skills. CWI PhD student Pablo Inostroza Valdera proposes to develop them by composing language fragments from software libraries, which makes this activity less laborious. He defends his PhD thesis at the UvA on 29 November 2018.

Two awards for CWI SWAT / INRIA collaboration at SLE 2018
Last week Tijs van der Storm and Thomas Degueule of CWI's SWAT group were awarded with two prizes at ACM SIGPLAN International Conference on Software Language Engineering (SLE) in Boston, Massachussets.
