Abstract In deductive verification and software model checking, dealing with certain specification language constructs can be problematic when the back-end solver is not sufficiently powerful or lacks required theories. One way to deal this transform, for purposes, program an equivalent one using constructs, reason about its correctness instead. paper, we propose instrumentation as a unifying p...

VerifyThis 2015 was a one-day program verification competition which took place on April 12th, 2015 in London, UK as part of the European Joint Conferences on Theory and Practice of Software (ETAPS 2015). It was the fourth instalment in the VerifyThis competition series. This article provides an overview of the VerifyThis 2015 event, the challenges that were posed during the competition, and a ...

Abstract VerifyThis is a series of program verification competitions that emphasize the human aspect: participants tackle detailed behavioral properties—something lies beyond capabilities fully automatic and requires instead expertise to suitably encode programs, specifications, invariants. This paper describes 8th edition VerifyThis, which took place at ETAPS 2019 in Prague. Thirteen teams ent...

Software verification is an established method to ensure software safety. Nevertheless, verification still often fails, either because it consumes too much resources, e.g., time or memory, or the technique is not mature enough to verify the property. Often then discarding the partial verification, the validation process proceeds with techniques like testing. To enable standard testing to profit...
