Opis

This book constitutes the refereed proceedings of the 17th International Conference on Theory and Applications of Satisfiability Testing, SAT 2014, held as part of the Vienna Summer of Logic, VSL 2014, in Vienna, Austria, in July 2014. The 21 regular papers, 7 short papers and 4 tool papers presented together with 2 invited talks were carefully reviewed and selected from 78 submissions. The papers have been organized in the following topical sections: maximum satisfiability; minimal unsatisfiability; complexity and reductions; proof complexity; parallel and incremental (Q)SAT; applications; structure; simplification and solving; and analysis.
