The success of SAT technology in the last decade is mainly due to both the availability of numerous efficient SAT solvers and to the growing number of problems that can efficiently be solved through a translation into SAT. If the main application in the early 2000 was bounded model checking, the current applications range from formal verification (in both software and hardware) to bioinformatics. The benefit of the incredible improvements in the design of efficient SAT solvers those recent years is now reaching our lives: The Intel Core7 processor for instance has been designed with the help of SAT technology, while the device drivers of Windows 7 are being certified thanks to an SMT solver (based on a SAT solver).
Designing efficient SAT solvers requires both a good theoretical knowledge about the design of SAT solvers, i.e. how are interacting all its components, and a deep practical knowledge about how to implement efficiently such components.
The SAT community organizes regularly SAT competitive events (SAT competition or SAT Races) to evaluate available SAT solvers on a wide range of problems. The winners of those events set regularly new standards in the area.
If the systems themselves are widely spread, many details on their design or in their implementation can only be found in the source code of the systems. This is also true for the encoding of some constraints. It is usually the case that system descriptions provided for the competitive events are not detailed and that the SAT conference publishes very few system descriptions since 2005 (before that, the post proceedings could contain the system description of the competition winners, e.g. Minisat for SAT'03 and Chaff 2004 for SAT'04).
The aim of the pragmatics of SAT workshop is to allow researchers concerned with the design of efficient SAT solvers at large or SAT encodings to meet and discuss about their latest results. The workshop is also the place for users of SAT technology to present their applications.
The first edition of that workshop took place during FLoC 2010. It ended up to be a great success, with more than 30 participants highly interested in the practical aspects of SAT and related problems. The second edition took place before SAT 2011, in Ann Arbor. It attracted also around 30 participants, and broadened the scope of the initial workshop to several applications (ATPG, software dependency management, etc). The third edition took place on June 16, 2012, between the second SAT/SMT Summer School (June 12 to 15) and the SAT conference (June 17-20). The workshop was a success (around 60 participants), many of them coming from the SMT summer school. The fourth edition took place on July 8, 2013, between the third SAT/SMT school and the SAT 2013 conference. The workshop attracted about 50 participants. The fifth edition took place the day before the SAT 2014 conference and the workshop attracted about 30 participants.
The sixth edition is taking place the day before the SAT 2015 conference.
Main areas of interest include, but are not restricted to:
The technical programme of the workshop is available as easychair smart program.
There is currently no central repository for SAT on which all the benchmarks and all the solvers which made the history of SAT are available. While those resources are available from the SAT Library (SATLIB), the SAT Competition web page and various individual web pages, they are subject to sudden unavailability when the authors of those web pages no longer maintain them.
There is thus a need to centralize those resources on a community managed web site (such as TPTP for instance) to make sure that their availability is guaranteed in the future and if possible that the solvers can still be run on future hardware and OS.
The aim of this panel is to discuss the various options for building such a repository "community-based", i.e. by dispatching as much as possible the maintenance of the repository to the community while in the same time ensuring the consistency of the resources available.
Registration is available from SAT15 web site.
The workshop welcomes three categories of papers:
Each submission will be reviewed by at least three members of the programme committee.
The papers must be submitted electronically through EasyChair as a PDF file using the EasyChair proceedings style. Each submission is limited to 14 pages, plus references. Accepted regular and work in progress papers will be available to the audience of the workshop and regular papers will be published in a volume of EasyChair in Computing electronic proceedings.
The SAT conference is now accepting tool papers, so there is no need to the push system descriptions as it has been done in the past. We welcome however extended versions of tool papers for detailed presentation during the workshop.
Note that it is still possible to submit system descriptions to the JSAT journal, at any time.
Authors should provide enough information and/or data for reviewers to confirm any performance claims. This includes links to a runnable system, access to benchmarks, reference to a public performance results, etc.
We warmly encourage the authors of the systems that enter SAT 2015 competitive events (SAT Race 2015, MAX-SAT 2015, PB Evaluation 2015, ...) to consider submitting a description of their solver to PoS, especially if they did not submit a tool paper to the main conferences.
