Sung-Shik Jongmans wins IPA Dissertation Award 2016

Research school IPA awarded Sung-Shik Jongmans with the IPA Dissertation Award 2016. The jury wrote: “The thesis contains theoretical contributions, novel ideas, and practical implementation results. The results have been impactful and are deemed to be of high quality and significance.”

EATCS Presburger Award 2017 for Alexandra Silva

The 2017 Presburger Committee has unanimously selected Alexandra Silva, a Senior Lecturer at University College London as recipient of the prestigious 2017 EATCS Presburger Award for young scientists. She received the award for a large part of her PhD research, which she carried out in the Formal Methods research group at Centrum Wiskunde & Informatica (CWI) in Amsterdam.

Cum laude for new method making parallel programming easier

Due to the increase of multicore processors used in smart phones, game consoles and other computers, parallel programming has become increasingly important. To prevent software errors, concurrent calculations must always exactly be executed in the correct order. This is not easy, because existing programming techniques for enforcing such orders - interaction protocols - are very hard to use. PhD student Sung-Shik Jongmans of Centrum Wiskunde & Informatica and Leiden University investigated a new programming method to simplify this.

FACS Best Paper Award for Formal Methods researchers

During the FACS2015 conference three researchers associated with the CWI Formal Methods research group were awarded the Best Paper Award for their article ‘Composing Constraint Automata, State-by-State’. The conference was held in Niterói, Brazil, from 14-16 October 2015.

Cum laude for PhD student Jurriaan Rot

Infinite data structures can be studied with a simplified technique, thanks to research done by PhD student Jurriaan Rot. He received his PhD degree with honours (cum laude) for his thesis ‘Enhanced Coinduction’ at Leiden University on 15 October 2015. This thesis belongs to the 5% best dissertations in the field of computer science.

TCS journal honours Jan Rutten

Jan Rutten from CWI’s Formal Methods research group was recently awarded by the journal Theoretical Computer Science (TCS) for his much cited article Universal Coalgebra – a theory of systems, on the occasion of the journal’s 40th anniversary.

Java Bug Fixed with Formal Methods CWI

Researchers from CWI fixed a bug in the widely used object-oriented programming language Java in February 2015. They found an error in a broadly applied sorting algorithm, TimSort, which could crash programs.

Better QoS for distributed software with stochastic and formal methods

Reusability of software is a hot topic nowadays. It is easier, cheaper and more efficient to reuse parts of existing software in order to adjust or incorporate new functionalities, than to design completely new programs. However, due to the different sources and constraints of software components, it is not easy to define the Quality of Service (QoS) for newly composed software, especially when it consists of components or services provided by various geographically distributed organizations. Young-Joo Moon, PhD student at the Centrum Wiskunde & Informatica (CWI) in Amsterdam, developed a stochastic formal model to derive the end-to-end QoS of such software systems.
