The aim of the Pragmatics of SAT (PoS) workshop is to allow researchers concerned with the design of efficient SAT and CP solvers at large or SAT encodings/CP formulation to meet and discuss about their latest results. The workshop is also the place for users of SAT and CP technology to present their applications. The collocation of CP, ICLP and SAT this year is a unique opportunity to enlarge the audience of the workshop to the whole constraint community, thus the specific name ``Pragmatics of Constraint Reasoning".
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. There are also numerous CP systems available today, in various languages, some of them hybridizing CP and SAT. Designing efficient solvers requires both a good theoretical knowledge about the design of those solvers, i.e. how are interacting all its components, and a deep practical knowledge about how to implement efficiently such components. The CP community organizes regularly competitive events (SAT competition or SAT Races, QBF Evaluation, MAXSAT evaluation, Minizinc Challenge, etc.) to evaluate available 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. The aim of the workshop is to allow researchers to share some gory technical details about their systems that they cannot usually share within the main SAT or CP conference.
