Symbolic Execution and Constraint Solving (Dagstuhl Seminar 14442)

This report documents the program and the outcomes of Dagstuhl Seminar 14442 "Symbolic Execution and Constraint Solving", whose main goals were to bring together leading researchers in the fields of symbolic execution and constraint solving, foster greater communication between these two communities and exchange ideas about new research directions in these fields. There has been a veritable revolution over the last decade in the symbiotic fields of constraint solving and symbolic execution. Even though key ideas behind symbolic execution were introduced more than three decades ago, it was only recently that these techniques became practical as a result of significant advances in constraint satisfiability and scalable combinations of concrete and symbolic execution. Thanks to these advances, testing and analysis techniques based on symbolic execution are having a major impact on many sub-fields of software engineering, computer systems, security, and others. New applications such as program and document repair are being enabled, while older applications such as model checking are being super-charged. Additionally, significant and fast-paced advances are being made in research at the intersection of traditional program analysis, symbolic execution and constraint solving. Therefore, this seminar brought together researchers in these varied fields in order to further facilitate collaborations that take advantage of this unique and fruitful confluence of ideas from the fields of symbolic execution and constraint solving

Synergies among Testing, Verification, and Repair for Concurrent Programs (Dagstuhl Seminar 16201)

This report documents the program and the outcomes of Dagstuhl Seminar 16201 "Synergies among Testing, Verification, and Repair for Concurrent Programs". This seminar builds upon, and is inspired by, several past seminars on program testing, verification, repair and combinations thereof. These include Dagstuhl Seminar 13021 "Symbolic Methods in Testing"; Dagstuhl Seminar 13061 "Fault Prediction, Localization and Repair"; Dagstuhl Seminar 14171 "Evaluating Software Verification Systems: Benchmarks and Competitions"; Dagstuhl Seminar 14352 "Next Generation Static Software Analysis Tools"; Dagstuhl Seminar 14442 "Symbolic Execution and Constraint Solving"; and Dagstuhl Seminar 15191 "Compositional Verification Methods for Next-Generation Concurrency". These were held in January 2013; February 2013; April 2014; August 2014; October 2014; and May 2015, respectively. Two notable contributions of Dagstuhl Seminar 16201, which distinguish it from these past seminars, are (i) the focus on concurrent programming, which introduces significant challenges to testing, verification and repair tools, as well as (ii) the goal of identifying and exploiting synergies between the testing, verification and repair research communities in light of common needs and goals
