SAT 2005 Special issue of the Journal of Automated Reasoning Guest Editors: Enrico Giunchiglia and Toby Walsh http://www.4c.ucc.ie/~tw/sat2005.txt In the last ten years, much progress has been made in our ability to solve problems in propositional satisfiability (or SAT) and related areas. In 2000, a very successful special issue of the Journal of Automated Reasoning and an accompanying book documented the progress made up to that time. In the subsequent five years, even more dramatic progress has been made. Systematic methods can now routinely solve verification problems with thousands or tens of thousanss of variables, whilst local search methods can solve hard random 3SAT problems with millions of variables. In light of this, we are planning another special issue of the Journal of Automated Reasoning, SAT 2005, on the state of the art for research into satisfiability in the year 2005. In addition to the special issue, the accepted papers will be published as a book which will be included as an optional extra in the registration package for the SAT-2005 conference. Topics We will consider empirical, theoretical or application oriented papers about SAT. Possible topics include complete and local search algorithms, applications (e.g. verification, finite mathematics, ...), extensions (e.g. non-clausal SAT, modal SAT, QBF, ...) and theory (e.g. worst-case analyses, random SAT, ...). We especially welcome submissions which document the implementation and other techniques developed in the last five years that have resulted in major improvements in the performance of SAT algorithms. Submission Please email a postscript or PDF file to Enrico Giunchiglia (giunchiglia@unige.it), and cc: a copy to Toby Walsh (tw@4c.ucc.ie). All submissions will be acknowledged. Timetable To ensure topicality of the special issue, submissions, reviewing and revision of papers will be held to very fixed and tight deadlines. Submission deadline 1 Nov 2004 Initial reviews returned 1 Feb 2005 Revised papers resubmitted 1 Mar 2005 Final decision 1 Apr 2005 LaTeX and PS files to Kluwer 1 May 2005
