Abstract

Whether working at the level of abstract design models or concrete loop-based code, inductive invariants play a pivotal role in specifying and reasoning about software systems. Inductive invariants capture design intuitions, so not surprisingly their generation represents a significant research challenge. In general, no single technique or approach will adequately address this challenge. Progress will most likely require novel integrations of complementary techniques and approaches. By promoting the exchange of ideas and experiences, the WING workshop series aims to support the development of such integrations. Engagement from across a number of fields is therefore a very important ingredient for a successful workshop. So we are delighted that this, the second WING workshop, has attracted a strong grouping of researchers, each bringing a different perspective on the challenge of invariant generation. This diversity is reflected in the submissions, which include both algorithmic and heuristic approaches to invariant discovery and verification. The use of novel formalisms, new logics and reasoning techniques are also well represented, while a diverse range of applications is good to see. We are delighted to have two excellent keynote speakers, Leonardo de Moura (Microsoft Research) and Andrey Rybalchenko (Max Planck Institute for Software Systems). Both have significant research expertise and insights into the challenges and opportunities for the growing WING community.
